Knockout Kings was the first boxing game that had an element of realism to it. Up until this point most boxing games were a little bit more on the fictitious size. What is really good about this game is the fact that you could box with some of the classic boxers. Sonny Liston versus Mohammed Ali is a fight we all would’ve liked to seen if both boxers were in their prime. But statistically the two boxing giants could box in this game. For all the classic boxing fanatics this game is a game you must own.
