Game economy systems play an important role in game design, not only limiting certain aspects of the game experience, but also supporting character development, rewarding players, facilitating social interaction, and introducing difficult choices. However, designing an efficient economic system is a daunting task. This article will start from the perspective of game design, introduce the basic knowledge of the economic system, and discuss some useful tools, techniques and design points to help designers design better games economic system.

#What is the economic system
The in-game economic system is similar to a real-life supply and demand market, revolving around currencies and resources. Some games have economic systems so complex that they even employ economists to publish economic reports. Benefits of the economy system include the efficient distribution of power, support for specialization, and facilitate player interaction and roleplaying. **However, not every game requires the same depth and complexity of the economy system. Currency and resources are a core part of any economic system.
# Currency and Resources
Simply put, money is a conventional medium of exchange used to purchase goods or services. The key is "exchange". In games, however, so-called currency isn't always real currency, but resources, used to gain extra life or protection. The nature of money has nothing to do with rarity or value, but rather its function as a medium of exchange. Currencies often have multiple uses, but they can also have limited uses. Resources play a key role in the currency system, and currency acts as a bridge between different parts of the player experience. At the same time, resources can exist completely without currency, or they can act as currency. **Resources have inherent value, which is usually assigned value by converting into currency. **Although currency and resources are often treated as the same concept in game design, by distinguishing them the relationship between them can be better understood and thus create more robust systems.
KEY POINT 1**: Identify in-game currency and resources. Controversial as it may be, taking this step helps to better understand the ecosystem of the world you are creating. **
However, an economic system is not just a list of currencies, it is also about the dynamic relationships between them: how they are converted, how they are produced, and how they are used and consumed. The terms commonly used in the industry to define these transformation relationships are "source" and "consume". **
#Source Sources and consume Sinks
Essentially, the two terms are pretty straight forward: Source** is the way you get currency,** like selling items, opening chests, or defeating enemies, and Consumption** is consuming currency Ways** such as buying items, dying or repairing and upgrading equipment.
Economic designers need to be concerned with two important aspects of these resource sources and consumption: how many sources and consumption points each currency will have, and the balance between these sources and consumption, which is what we call "generosity".
source and consume quantity
In the game, the number of source and consumption points is not strictly regulated. There can be multiple sources fed into a single consumption point, or only one source (for example, the loot obtained by defeating the boss in a Roguelike game), and the end-stage system can be opened by providing the consumption point of the corresponding currency. The sources and depletion points required for each currency depend on the game system and expectations of the player experience. Multiple ways to obtain currency can promote player freedom of choice and personality expression (provided the source is balanced). If the game encourages specific systems to engage or rewards specific actions, designing a dedicated currency will immediately motivate players (or create critical bottlenecks in major processes).
Having multiple spendpoints gives the player meaningful choices and priorities (e.g., "what to buy?" or "what to buy first?"), while only one spendpoint focuses player action and gameplay on one unmissable on the target.
Key point 2: By determining the source of currency and the number of consumption points, determine the player's initiative and progress in the game
Now, let's talk about a much-talked-about topic in the game.
generosity
Generosity is critical to player engagement in the economy, depending on the balance between sources and points of consumption. Being overly generous can cause players to lose interest, while not being generous enough can cause players to abandon the game. **Balance is key.
Excessive generosity can be beneficial in the short term****, but** can be disastrous in the long run, weakening game systems and affecting player motivation. Either extreme will cause the player to leave the game. Therefore, finding the right level of generosity is critical to keep players interested and engaged.
**# Key point 3: Being overly generous or not generous enough will lead to a decline in player motivation, and designers should track and adjust carefully. **
Trying both extremes at different stages of the player experience is a viable suggestion. At the beginning of the game, over-generosity (sources exceeding consumption) can give players a strong sense of control and progression, enticing them to keep playing. This taps into people's psychological need to like to hoard, bringing an instant sense of victory. As the game progresses, the player's wants and needs become more specific and defined. In this change, reducing sources and increasing consumption will better serve these desires, increasing player retention and the need to master the game.
The following diagram simplifies the balance of money over time:
**# Key point 4: The balance between the source and consumption of currency can change over time: use this relationship to guide player behavior to meet their current needs and motivations. **
Of course, in design every situation is unique and this balance can take many different forms: don't be afraid to experiment and find the perfect balance for your game. For example, in a free-to-play game, you can get very different curves when you have twice as much hard money (real money) as you do soft money (virtual money in the game). In the example below, we first have an "attraction" period, during which buying currency is not necessary, and then the balance suddenly reverses, severely limiting the player's game progress once the "trial" period is over:
To balance sources and consumption, designers can use a global metric: **Currency gain per minute. **This metric tells us how much currency a player can get within a certain timeframe, allowing us to adjust consumption points. Applying this metric to the entire game provides clear design direction, while applying it to each system creates opportunity. ** Giving slightly more currency in a certain system relative to the global average is an effective way to incentivize players to participate in that system. **
This approach makes players feel like they can get more currency by choosing a certain system in the same amount of time. Is this a planned design? Does this provide a better experience?
**# Key point 5: Determine the amount of player's global currency gain per minute, and then make adjustments for each system to adjust consumption points accordingly, helping to shape the overall game experience. **
With all that said, to summarize what we've defined here: A game's economy system consists of all the currencies and resources, and how they relate to every system in the game. It plays a central role in the player's gaming experience and greatly influences how players play and engage. Currency is a medium of exchange, which is exchanged through sources and consumption, and the balance between sources and consumption has an important impact on player motivation and retention.
Designing an economic system is not easy, and one of the biggest difficulties is not knowing where to start. In the following, some useful methods are introduced.
#Breadwinner
Before designing an economic system, it is important to determine the application domain of the currency. And not just listing different game systems. Instead, we should be thinking about how **aspects or pillars in the game can be enhanced by the economic system, and whether there is a relationship between them. **For example, the Exploration pillar can be fulfilled by rewarding players for discovering scarce resources in a region. COOPERATION/SOCIAL Pillars can be circulated and value-added between players through currency, which can be used to purchase community goods to strengthen cooperation and interaction. END GAME PHASE Gives a new endgame experience by unlocking unique shops and upgrades with micro-currency earned from beating the game's highest challenges. In design, we can order these ideas according to the importance and connection of pillars.
PLEASE NOTE: Games don't need to have too many economic pillars (or game pillars). Take enough time to properly define what really makes up your game and includes all of the game mechanics.
** # Key Point 6: Start by carefully defining and mapping the game's economic pillars and understanding how they relate to each other. This will help provide an extremely solid foundation. **
Now that we have this foundation, we can start creating currencies! But first how many currencies do we need?
#Amount of Currency
When designing a game economy system, determining the amount of currency required is a complex question with no definitive answer. At one extreme there is only one currency, tied to all systems, which can cause the player to lose the sense of game limitation. At the other extreme is having several currencies, each microsystem has its own currency, but this can reduce player initiative and game continuity.
A good design should find the right point in the balance. For example, Hades divides money into three main pillars, each with its own sources and consumption. This design matches the core mechanics of Rogue-Like games, providing the basis for an efficient game loop that encourages players to try again and provides the best possible gaming experience.
Therefore, designers need to comprehensively consider factors such as game type, player motivation, and system interaction to find the economic system balance point suitable for the game.
Key point 7: The amount of currency required will be constrained by the system, the relationship between them, the game's requirements for player initiative and freedom, and the protection mechanism that needs to be set up for key systems
suggestion:
Currency is the most basic reward: In every game loop, the reward is the core, whether it is extrinsic or intrinsic. And the simplest and most basic reward for players is some currency. It is recommended to use sufficiently segmented currencies to provide these small rewards.
Currency exchange with caution: There used to be many systems that failed because of things like this: gems could be exchanged for gear, gear could be exchanged for gold, gold could buy tokens, tokens could... eventually, all of these currencies Interrelated, forming a unified monetary system, brings with it many potential problems. Be cautious about exchanging between these currencies, or limit them as appropriate. The poor broker in Hades offers a way to exchange money, but at a very high cost.
Design Currencies to Meet Different Player Styles: There are multiple ways to create currencies to achieve specific goals. An efficient solution is to combine it with the game economy and core gameplay. Another approach is to consider how players engage in the game: rewarding them for time investment (e.g. killing monsters), rewarding performance of their skills (e.g. defeating bosses or completing achievements), or even rewarding their loyalty (e.g. gifting gift or common currency across games).
There is also a particularly effective approach when designing a currency with a specific goal:
Currency Semantics
For each currency, list the associated verbs as follows:
Gold Coins: Loot/Sell/Buy/Repair/Win/Acquire
Diamonds: find/exchange/reward/steal/protect
Iron Ore: Smelt/Trade/Negotiate/Haggle/Upgrade
other
Doing so highlights interactions between different currencies and helps you focus on specific currencies, delete or create new ones. At the same time, this will also bring new system ideas, which may not have been considered before, to further enhance the game experience. Storing diamonds, for example, could make you a target for thieves, and the more diamonds you store, the more protection you'll need.
**Key point 8: Mapping currency semantics! This is an easy way to understand their domain of action and provide new ideas to enrich the system! **
Player Value and Evolution
Before closing the currency discussion, there is one last aspect to talk about: the value of money over time. This is not referring to the value of the game, but the value to the player: the value of the game's currency in the eyes of the player and how it changes over time. **
In simple terms, this value will fluctuate continuously in the player's game experience and game progress. Here are two fairly common examples.
There is usually a soft currency in the game, such as gold coins, as the main currency. In the initial stage, gold coins are the most valuable resource, and players can use them to buy almost everything. However, as time goes by, the player gets richer, fewer items are available to buy, and the value of the currency gradually decreases. Eventually, players will reach a point where gold loses value to them, and related systems fade away. This is a common situation in many games.
At the end of the game, there is a currency that serves no purpose to the player at the beginning of the game's journey (such as a "quest pass" similar to a team challenge). However, as players approach the endgame stages, they gradually learn about the existence of this currency and begin to appreciate its importance and value growth! Ultimately, when the game systems associated with this currency really open up (such as unlocking quest events or reaching required levels or achievements), it will become one of the most valuable currencies and one of the main drivers in the game experience for players !
Aside from these classic examples, what's even more interesting is what happens when you combine them:
One currency will naturally replace another over time, this evolution will have ripple effects throughout the player's overall gaming experience, including different goals, motivations, rewards and systems, etc. By carefully predicting the mapping between each currency and player value, not only can their relevance be ensured, but the game systems associated with each currency and the incentives for players to engage with these systems can be controlled. A recession in a currency can be a good thing and can be engineered for!
**#KeyPoint9 Project the value of currencies in the player's mind over time, and think about how they compete with each other at different stages of the player's journey. **
#Inflation, deflation and a destructive economy
When discussing the economic system, there is a worrying word that is often involved: **inflation. ** It is generally accepted that it is the worst thing that can happen to the economy and strives to avoid it. However, the reality is much more complicated (especially for game designers).
Inflation and deflation are two sides of the same coin, closely related to supply and demand, and directly affect the purchasing power of money. In real world economies, these values are so sensitive that central banks take active steps to control them. However, simple translation of real-world models and solutions into games is not suitable, as virtual economies are often too simplified to be self-sustaining in the long term.
Example
Take "Diablo 2" as an example, the game revolves around one currency: gold coins. Unlike the real economy, players can continuously create gold coins, obtained from defeating monsters or opening treasure chests. In multiplayer games, players have accumulated a large amount of gold coins, ** causing the gold coins to lose value, ** can not be used to buy high-level items, and there is no backup currency in the game to solve this problem. So players began to barter, forming a commodity currency based on the "Stone of Jordan", which became the rarest and most valuable ring. This forms a secondary economic system dominated by players.
The in-game economy is influenced by game mechanics. With store items priced the same, they become almost free, and the currency devalues to zero, causing game progression and parts of the core loop to become irrelevant. GTA is an interesting case of inflation that spreads through the single player experience. As players put in a lot of time, the total amount of money grows uncontrollably, leading to hyperinflation. The developers took steps to control currency liquidity, introducing new systems and items that require more currency to buy, both preventing players from destroying the game economy and providing new rewards for loyal players while burning currency. However, it also exacerbates the wealth gap, excludes new players from joining, and causes item prices to skyrocket to ridiculous levels.
In the case of World of Warcraft, for example, the game's economy is handled significantly differently than other games. Gold coins kept piling up without a corresponding increase in the price of items, which led to deflation. The auction house is flooded with items looted by farmers and bot players, eager to exchange their loot for more currency, causing item prices to drop.
World of Warcraft has taken the interesting approach of rebalancing the economy with each new expansion release. Introducing expensive new items to incentivize wealthy players, and rebalancing the entire economy to increase access to gold to ensure new players get in on the action. However, there are obvious downsides to this approach: the devaluation of gold coins causes players to lose a lot of wealth, and player engagement can drop from one expansion to another.
In summary, Creating a robust and sustainable virtual economy based on the examples described above is impossible. There are too many defects in the game economy: virtual currency is generated infinitely, and players can hoard it without spending it. The generosity of game design leads to an unbalanced system that does not meet the needs of every player. In short, the game economy was doomed from the start.
**# Key point 10: The game economy will collapse. Accept this fact early to anticipate the impact of this depreciation. **
Below are possible options for dealing with a bad situation.
Safeguards and Currency Protection
Here are a few ways to alleviate game economy issues:
**Remove or tax multiplayer components: **one of the most straightforward methods. Keeping the currency flowing around the player gives more control over how it grows and is used.
** Increase and specialize currencies: ** Introduce different types of currencies and reduce their influence to better control and protect the economic system.
**Destroyed transaction: **By establishing a system for destroying excess currency, offset the currency that players continue to generate.
Maintenance System: Requires players to pay for items they own, such as apartment tax, weapon repair costs, guild tax, etc. This method is efficient and can be adjusted according to the player's wealth level to control the currency circulation, but it may also be viewed as a bondage by the player.
Wallet Limits: Limit the amount of currency players can carry and store, forcing them to spend to keep earning more. Combined with a currency burn mechanism, a secure economic base could be established, but this could also be seen as artificially restrictive.
Economic Rebalancing: Tweaks to the economy system, rebalancing resources and consumption to keep player currency within acceptable limits. This method is efficient, but can leave even the most loyal players feeling cheated.
**#KeyPoint11: Consider what factors can build strong defenses to delay currency devaluation. **
In the above, a seemingly obvious solution has not been mentioned: have a finite amount of currency! After all, this is one of the keys to building a stable real world economy, and one of the reasons why governments are so cautious about printing more money! Unfortunately, however, some old-fashioned MMORPGs (which is one of the reasons for Ultimate's economic collapse) tried this method, but the result was always the same: ** Players hoard currency, while there is no Obligated to spend these currencies, causing the economy to come to a complete standstill, effectively disappearing from the game world. **Even such a marvel of an economic system as Eve Eve retains some robust ISK (core currency) creation and destruction systems. It's worth noting that one of the keys to success in this endeavor will be the creation of a completely player-managed economy (banks, shops that set the prices of all items in the game, etc.) and enforce strict protections Measures such as spoilage to prevent hoarding, influential taxation systems, or devaluation of currency when it is stored to promote consumption.
If we try to simply visualize these solutions, we should be aiming for the following in terms of player value over time:
It's not perfect, but it slows down time! Maybe this is the time to wait for a new extension or some other currency alternative...
# draw economic system map
Organize and transform all information into possible focus points for documentation in the design workflow. During the design phase, the following three essential documents are recommended, which start at a high level, are designed to drive your vision for the economy, and serve as guiding principles for design, implementation, and iteration.
The first document provides a general overview of the entire system, including:
Breadwinner
Position of each currency in its corresponding pillar
Mobility and exchange possibilities between currencies
Although this is a simplified view, it is useful for applying it to your system.
In this simple example, we can clearly see the following:
Gold is the primary currency, used in exchange and as a medium of exchange.
Diamonds are the most valuable currency and can be exchanged for almost anything.
The currency generated by narrative/mission is strictly controlled and cannot be obtained through other systems, but can be generated by gold to meet exploration needs.
Prestige tokens may be an advanced end-stage currency that is gradually introduced and plays an important role in the game. It exists on its own.
The second document is a continuation of the previous document and is optional. It will synthesize the previous overview with the flow of each system, including sources, consumption and the linkages between them.
Here's a quick example about "iron" in a fictional game.
This document can become very large, **it is recommended to only create it if your game has a dense, complex and intertwined economy system (such as building classes, strategy games, etc.). **
The last document is actually the one we've already discussed in this article: it's a complete representation of your expected player value for each currency over time. Here's a quick example:
This document plays a central role in the design. While it may be somewhat theoretical, it provides a clear vision of the system and player motivations. The following simple diagram conveys the following information:
Iron is a starting resource that gradually decreases in value and has a role in the early game.
Gold is the resource of choice and needs to remain relevant, with controls and price adjustments to keep value declines in check.
Diamonds are the most valuable resource with a stable value and remain important at the end of the game.
Introducing a precious hard currency that is ubiquitous and the only consumable in advanced systems, maintaining constant value.
Prestige tokens become the main driving force for players to enter the final stage, and their value may exceed hard currency.
As the game evolves, different currencies and systems drive player motivation and engagement. The obvious stages are early/mid and late players.
By building your game with these assets and currencies, you gain a complete view of what needs to be created and receive clear guidance while testing and validating expected outcomes. The purpose of the documentation is to provide guidance and visualize complex economic systems.
#in conclusion
This article cannot exhaustively cover all aspects of economic design, but by applying key points, tools, and ways of thinking, it can help create, maintain, and optimize efficient virtual economic systems. Constantly iterating, testing, and tweaking is key, and focusing on the human element is one of the complexities. Here is the last key takeaway:
**Key point 12:****Continuously iterate, test and make more improvements. The economic system in the first draft couldn't be perfect because it involved many elements, one of the most complex being people. Always pay attention to the progress and development of the economic system. **

Ultimately, when the game systems associated with this currency really open up (such as unlocking quest events or reaching required levels or achievements), it will become one of the most valuable currencies and one of the main drivers in the game experience for players !
Aside from these classic examples, what's even more interesting is what happens when you combine them:
One currency will naturally replace another over time, this evolution will have ripple effects throughout the player's overall gaming experience, including different goals, motivations, rewards and systems, etc. By carefully predicting the mapping between each currency and player value, not only can their relevance be ensured, but the game systems associated with each currency and the incentives for players to engage with these systems can be controlled. A recession in a currency can be a good thing and can be engineered for!
**#KeyPoint9 Project the value of currencies in the player's mind over time, and think about how they compete with each other at different stages of the player's journey. **
#Inflation, deflation and a destructive economy
When discussing the economic system, there is a worrying word that is often involved: **inflation. ** It is generally accepted that it is the worst thing that can happen to the economy and strives to avoid it. However, the reality is much more complicated (especially for game designers).
Inflation and deflation are two sides of the same coin, closely related to supply and demand, and directly affect the purchasing power of money. In real world economies, these values are so sensitive that central banks take active steps to control them. However, simple translation of real-world models and solutions into games is not suitable, as virtual economies are often too simplified to be self-sustaining in the long term.
Example
Take "Diablo 2" as an example, the game revolves around one currency: gold coins. Unlike the real economy, players can continuously create gold coins, obtained from defeating monsters or opening treasure chests. In multiplayer games, players have accumulated a large amount of gold coins, ** causing the gold coins to lose value, ** can not be used to buy high-level items, and there is no backup currency in the game to solve this problem. So players began to barter, forming a commodity currency based on the "Stone of Jordan", which became the rarest and most valuable ring. This forms a secondary economic system dominated by players.
The in-game economy is influenced by game mechanics. With store items priced the same, they become almost free, and the currency devalues to zero, causing game progression and parts of the core loop to become irrelevant. GTA is an interesting case of inflation that spreads through the single player experience. As players put in a lot of time, the total amount of money grows uncontrollably, leading to hyperinflation. The developers took steps to control currency liquidity, introducing new systems and items that require more currency to buy, both preventing players from destroying the game economy and providing new rewards for loyal players while burning currency. However, it also exacerbates the wealth gap, excludes new players from joining, and causes item prices to skyrocket to ridiculous levels.
In the case of World of Warcraft, for example, the game's economy is handled significantly differently than other games. Gold coins kept piling up without a corresponding increase in the price of items, which led to deflation. The auction house is flooded with items looted by farmers and bot players, eager to exchange their loot for more currency, causing item prices to drop.
World of Warcraft has taken the interesting approach of rebalancing the economy with each new expansion release. Introducing expensive new items to incentivize wealthy players, and rebalancing the entire economy to increase access to gold to ensure new players get in on the action. However, there are obvious downsides to this approach: the devaluation of gold coins causes players to lose a lot of wealth, and player engagement can drop from one expansion to another.
In summary, Creating a robust and sustainable virtual economy based on the examples described above is impossible. There are too many defects in the game economy: virtual currency is generated infinitely, and players can hoard it without spending it. The generosity of game design leads to an unbalanced system that does not meet the needs of every player. In short, the game economy was doomed from the start.
**# Key point 10: The game economy will collapse. Accept this fact early to anticipate the impact of this depreciation. **
Below are possible options for dealing with a bad situation.
Safeguards and Currency Protection
Here are a few ways to alleviate game economy issues:
**#KeyPoint11: Consider what factors can build strong defenses to delay currency devaluation. **
In the above, a seemingly obvious solution has not been mentioned: have a finite amount of currency! After all, this is one of the keys to building a stable real world economy, and one of the reasons why governments are so cautious about printing more money! Unfortunately, however, some old-fashioned MMORPGs (which is one of the reasons for Ultimate's economic collapse) tried this method, but the result was always the same: ** Players hoard currency, while there is no Obligated to spend these currencies, causing the economy to come to a complete standstill, effectively disappearing from the game world. **Even such a marvel of an economic system as Eve Eve retains some robust ISK (core currency) creation and destruction systems. It's worth noting that one of the keys to success in this endeavor will be the creation of a completely player-managed economy (banks, shops that set the prices of all items in the game, etc.) and enforce strict protections Measures such as spoilage to prevent hoarding, influential taxation systems, or devaluation of currency when it is stored to promote consumption.
If we try to simply visualize these solutions, we should be aiming for the following in terms of player value over time:
It's not perfect, but it slows down time! Maybe this is the time to wait for a new extension or some other currency alternative...
# draw economic system map
Organize and transform all information into possible focus points for documentation in the design workflow. During the design phase, the following three essential documents are recommended, which start at a high level, are designed to drive your vision for the economy, and serve as guiding principles for design, implementation, and iteration.
The first document provides a general overview of the entire system, including:
Although this is a simplified view, it is useful for applying it to your system.
In this simple example, we can clearly see the following:
The second document is a continuation of the previous document and is optional. It will synthesize the previous overview with the flow of each system, including sources, consumption and the linkages between them.
Here's a quick example about "iron" in a fictional game.
This document can become very large, **it is recommended to only create it if your game has a dense, complex and intertwined economy system (such as building classes, strategy games, etc.). **
The last document is actually the one we've already discussed in this article: it's a complete representation of your expected player value for each currency over time. Here's a quick example:
This document plays a central role in the design. While it may be somewhat theoretical, it provides a clear vision of the system and player motivations. The following simple diagram conveys the following information:
As the game evolves, different currencies and systems drive player motivation and engagement. The obvious stages are early/mid and late players.
By building your game with these assets and currencies, you gain a complete view of what needs to be created and receive clear guidance while testing and validating expected outcomes. The purpose of the documentation is to provide guidance and visualize complex economic systems.
#in conclusion
This article cannot exhaustively cover all aspects of economic design, but by applying key points, tools, and ways of thinking, it can help create, maintain, and optimize efficient virtual economic systems. Constantly iterating, testing, and tweaking is key, and focusing on the human element is one of the complexities. Here is the last key takeaway:
**Key point 12:****Continuously iterate, test and make more improvements. The economic system in the first draft couldn't be perfect because it involved many elements, one of the most complex being people. Always pay attention to the progress and development of the economic system. **
