Game Theory might be better described as Strategy Theory, or Theory of Interactive Decision Making. A strategic situation involves two or more interacting players who make decisions while trying to anticipate the actions and reactions by others. Game theory studies the general principles that explain how people and organizations act in strategic situations.

Game theory studies strategy mainly through the analysis of different "games". A "game" in game theory is a fully explicit structure within which players (agents) act strategically to maximize personal Utility. Games provide a simplified world within which to study strategy (as opposed to the real world where complexities get in the way of developing general principles).
