AKI is the developers that made the awesome WWF No Mercy, and the wCw games for the Nintendo 64, widely hailed as the greatest wrestling games of all time.
They used the engine from those games in the first Def Jam, which is why that is a "wrestling" type game. In the sequel they removed a lot of stuff from the engine, and in this one, they completely removed the engine altogether, which is why I think ths one will suck.
