What made Def Jam so good was the AKI engine used in the old N64 games, EA made a pretty stupid ass decision though as the next Def Jam games on the next generation sysatems will not use this engine, instead they're going for an all striking style of gameplay. Back to Fire Pro, if you havn't played it, you need to check the shit out, you can counter pretty much every move, the animation and transition in the moves is natural , lots of styles of matches you can have ranging from shoot fights in the octagon to Japanese death matches with exploding cages. Lots of wrestlers and grapplers ranging from indipendant federations to Japanese and American federations such as the WWE and old school ECW and WCW, as well as shoot fight organizations like PRIDE FC and UFC. There's a new Fire Pro game coming out, called Fire Pro The Return, can't remember for what system though...
