This paper considers solo games (one player against the computer) and the point of view of the game analyst or the game designer is taken and it is shown that game theory can be a power full tool.
Numerous authors have tried to use game theory as a tool for computer game design and study. These works recall generally some basic concepts of the Neuman Mogenstern game a nalysis (payoff matrix, finite zero-sum game, dominant and mixed strategy...) and show how to model and interpret some simple gameplay situation. In this paper we consider solo games (one player against the computer) and we take the point of view of the game analyst or the game designer. Game theory is e ither used to understand the gameplay or to build a gameplay. In this case game theory hypothesis are never met: the computer has a ll the knowledge and is in charge to disclose the game rul es to the player according to a driven progression scheme. But we sh ow t at, as the game designer is the creator of the universe of the game, he can choose the rules, the payoff matrices and the laws of the video game universe, that game theory can be a power full tool.
