To be fully defined, a game must specify the following elements: While it would thus be optimal to have all games expressed under a non-cooperative framework, in many instances insufficient information is available to accurately model the formal procedures available to the players during the strategic bargaining process, or the resulting model would be of too high complexity to offer a practical tool in the real world. A set of strategies is a Nash equilibrium if each represents a best response to the other strategies.
