Which choice will a player make if he can make one of two choices in which his own payoffs are equal, but his rival’s payoffs are not equal, i.e. one with a large payoff for his rival and the other with a small payoff for his rival? This paper introduces non-altruistic equilibria for normal form games and extensive form non-altruistic equilibria for extensive form games as equilibrium concepts of noncooperative games by discussing such a problem and examines the connections between their equilibrium concepts and Nash and subgame perfect equilibria that are important and frequently encountered equilibrium concepts.
