Renewable Resources

The one-sentence "definition" that should be in italics.

This pattern is a still a stub.

Examples

Dungeons & Dragons 4th edition powers once per encounter once per day

Legendary: Encounters Reshuffle draw piles once so weak example

Fury of Dracula - The Dracula player has 5 cards that can be used to evade capture or trigger events. These can't be re-used until the card drops off the trail spaces.

Using the pattern

Renewable Resources is used to ensure that Resources are continuously introduced into game instances, although this characteristic may be disrupted by players. Designing for their presence in games mainly consist of deciding which Resources should be renewable and under what conditions they renew. Specific ways of making Resources renewable include having Chargers, Pick-Ups, Producers, Spawning, and Controllers together with Resource Generators. While all these related to specific points in Game Worlds, Renewable Resources can also be achieved in more abstract ways through Game Element Insertion, No-Use Bonus, or Regenerating Resources. Designed Closed Economies by definition renew Resources, at least as long as differences are made between different states of more abstract Resources or if some states of Resources are seen as locked or hidden. They are often necessary in Persistent Game Worlds to avoid complete depletion or the Resources being hoarded in specific places or states. Quite obviously, Renewable Resources isn't compatible with Non-Renewable Resources.

Typical examples of Resources that can be renewed include Budgeted Action Points, Extra Chances, Health, Lives, and Units.

Can Be Modulated By

Converters, Ownership,

When Renewable Resources are renewed automatically this is practically an example of applying a Time Limit. When renewing them are instead actions, being able to do so can be Privileged Abilities for Characters. Renewable Resources can by affected by Resource Caps to create maximum amount of Resources available to individual players or to the game state as a whole. Another, and compatible option, is to use Diminishing Returns so that the Resources replenish slower if there are many of them.

Consequences

Renewable Resources can make the number of usable Resources greater over a game instance than what is available at a specific point of time due to Limited Resources or Resource Caps. Figuring out how to much Renewable Resources can be used without depleting there ability to renew is a form of Resource Management, and can turn into situations where Tradeoffs need to be made between short-term needs and long-term benefits. Renewable Resources often gives rise to Social Dilemmas when several players can make use of them since overuse from any one player can affect all negatively.

Resource Caps on Renewable Resources can created Encouraged Constant Player Activity since players need to consume the Resources to most efficiently make use of them. This in itself is a form of Resource Management. The presence of Renewable Resources affects the usefulness of Mules since without them the Mules can most likely only be effective for short periods of time.
