Knockout Kings 2003

Knockout Kings is a series of boxing video games that were produced by EA Sports for the PlayStation, Nintendo 64, PlayStation 2, Xbox, Game Boy Color and GameCube yearly between 1998 and 2003. Before releasing the first Knockout Kings, Electronic Arts released its first 3D boxing game, Foes of Ali, for the 3DO in 1995. While there are a few similarities between the two games, Foes of Ali was developed by a different team, Gray Matter and as such, is not regarded as a true prequel.
