For games that use resources to possess the right level of challenge the availability of resource has to be restricted. This means that players have Limited Resources in some sense and have to make use of them in the most efficient way to play the game as well as possible.
Example: in Chess the players have sixteen pieces each and there is a clear threat of losing these resources.
Example: even though it is possible to build more troops in WarCraft the game is balanced in such way that there is always a need for planning the use of the troops and also a feeling of the possibility of running out of them.
Limited Resources can be used together with both Non-Renewable Resources and Renewable Resources. The main point in both cases is, however, to control the amount of Resources available to the player at any certain point of gameplay in such way that the player is always forced to plan and to make Tradeoffs when using the Resources. This is often used by having some form of Container that limits the amount of Resources available, and the capacity of the Container, in turn, can be modulated by Improved Abilities or Decreased Abilities to modulate how limited the Resources are. Ways of combining Limited Resources and Renewable Resources may be that it is possible to gain new Resources from Pick-Ups or Resource Generators but either the Resources must be used far from these or that the amount of Renewable Resources are limited.
Limited Resources decrease players' Freedom of Choice. In principle all games have Limited Resources, but often some of the Resources are more limited than the others forcing the player to plan and form strategies about the use of these resources. The amount of available Resources limits the possible actions and strategies of the players, and thereby their Freedom of Choice. Limiting the amount of Resources available to the player reduces the potential actions possible for the player, increases Stimulated Planning and, in some cases, gives a method to avoid Analysis Paralysis. Planning how to use Limited Resources is one of the corner stones of Resource Management and skill in making most use of Limited Resources, and especially in making correct Risk/Reward judgments and often basis for Game Mastery.
