How Video Game Economies are Designed

New Section

This section introduces the concept of video game economy design and its importance in shaping player behavior and gameplay progression. The speaker also mentions a specific exploit in The Witcher 3's economy that was later fixed by CD Projekt Red.

Introduction to Video Game Economy Design

• Video game economy refers to the flow of resources within a game system.

• Resources can include coins, crafting materials, experience points, etc.

• Taps generate new resources into the economy, either automatically or through manual mining by players.

• Taps can incentivize player behavior and affect resource scarcity and value.

• The inventory holds collected resources, which may have an upper limit to create challenging decisions for players.

• Converters allow players to exchange one resource for another, such as buying gear or crafting items.

• The cost of conversion can impact the pace of the game's progression.

• Careful design of converters can encourage decision-making in players.

Examples from Games

• Ghost of Tsushima has multiple crafting materials linked to specific upgrades, reducing decision-making complexity.

• Metro: Exodus has only two crafting materials required for various items, forcing players to be intentional with their choices.

New Section

This section explores how video game economies can influence player decision-making and provides examples from different games.

Impact on Player Decision-Making

• Well-designed economies can encourage players to make thoughtful decisions about resource allocation.

• In-game shops require players to decide how to spend limited currency.

• Crafting systems with limited resources force players to prioritize their needs.

Examples from Games

• Ghost of Tsushima has simplified decision-making due to direct material-to-upgrade links.

• Metro: Exodus creates more strategic decision-making by requiring components and chemicals for all crafted items.

What Makes Grinding in Video Games Fun?

In this section, the speaker discusses the concept of grinding in video games and explores different ways to make it more interesting or less tedious.

The Purpose of Exchanging Resources

• Players exchange resources in games to become more powerful, efficient, or resilient.

• Obtaining bigger swords and better armor prepares players for upcoming challenges.

Repeating Content with Better Gear

• Some games allow players to return to previously visited areas with improved gear, stats, and health.

• This can be a fun aspect of idle games and roguelikes with permanent progression.

Positive Feedback Loop and Grinding

• Repeating content to amass power creates a positive feedback loop.

• This system reinforces the output more strongly but can also be addictive.

• However, repeating the same content slowly for power accumulation is often referred to as grinding.

Addressing Power Creep

• There are ways to address or minimize the power creep feedback loop.

• CD Projekt Red introduced a cryptic addition called the "bovine defense force initiative" in a patch for fixing an exploit in their game.

Making Power Creep More Interesting

• One approach is to turn power creep into a puzzle or complex problem-solving challenge.

• Games like Factorio, Satisfactory, and Stardew Valley offer gameplay that requires optimization and efficiency.

Implementing Negative Feedback Loop

• Another method is implementing a negative feedback loop that balances itself towards a status quo.

• Elden Ring graphically demonstrates increasing costs for leveling up as players progress. This discourages repetitive tactics by making them ineffective.

Slowing Down Grinding with Drains

• Introducing drains, which permanently remove resources from the economy, can slow down grinding.

• Examples include breakable weapons, health loss, unit loss, taxes, and ammo depletion.

• Drains can also add risk and encourage players to explore new strategies and options.

Lecture on Video Game Economies Understanding the Different Types of Economic Entities in Games

In this section, the speaker discusses the different types of economic entities in video games and how they contribute to gameplay. The entities include taps, inventories, converters, drains, and traders.

Taps: Creating Resources

• Taps are mechanisms that create resources in a game.

• They can be compared to sources or generators of resources.

• Examples include resource-generating buildings or actions performed by players.

Inventories: Storing Resources

• Inventories are where resources are stored in a game.

• Players can accumulate and manage their resources within their inventory.

• Inventories can have limited capacity or specific rules for storing certain types of resources.

Converters: Exchanging Resources

• Converters allow players to exchange one type of resource for another.

• They can be simple, like vending machines that convert money into items.

• In more complex games, converters may involve shops with unique inventories and pricing systems.

Drains: Losing Resources

• Drains represent mechanisms that cause players to lose resources in a game.

• Losing resources through drains can create negative feedback loops and hinder progress.

• An example is losing money in Monopoly, which reduces a player's ability to compete with others.

Traders: Buying and Selling Resources
