Good competitive multiplayer games need to be fair. As fairness is a multifaceted topic, it is interesting to approach subsections of the whole game and to find aspects that make the game fair. This work approaches the gamespace specifically, on the search for general principles of fair gamespaces, applicable to a broad range of games. Furthermore, this work proposes a formalization, which allows developers to analyze gamespaces at any point of the development process, and to check whether the proposed principles are fulfilled. To put this way of analysis to the test, we apply it to the Summoner’s Rift, the most relevant gamespace of the successful Multiplayer Online Battle Arena "League of Legends".
