Talking about games without a shared technical language becomes a tricky proposition rather quickly. I’ve been using a series of terms often among my circle of like-minded friends and I thought some definitions were in order. The purpose of these definitions is to be functional to the exploration and analysis of games; in that way, they help us understand each other better. They are all subject to improvements and suggestions are always welcome.
- Challenge
- A test of one’s abilities or resources towards achieving a particular goal. A group of activities that share a common purpose on a strategic, if not necessarily on a tactical, level.
The next two definitions are used to describe certain aspects of challenges.
- Error tolerance
- A combination of the severity and quantity of errancy allowed to the player before the challenge is failed.
- Cost of failure
- A combination of game world and real world elements that are exchanged by the player to be allowed to continue playing once a challenge has been failed.
