King of Colosseum (2002) for PlayStation 2 was a landmark for realism, featuring licensed rosters from NJPW, AJPW, and Pancrase. This crossover created unprecedented dream match potential, letting fans pit puroresu legends against MMA fighters in simulation-style bouts. Presentation was authentic, with lifelike entrances, arenas, and commentary.
