According to ESRB, this game contains: Animated Violence, Mild Language
Parents, this is a respectful and serious recreation of the sport of boxing. If youre child loves boxing, this title may have gameplay problems, but its still probably your best bet if you want a realistic simulation of the sport (complete with bloody cuts and illegal low blows). Otherwise, if you prefer the sport with more cartoonish violence and antics, go to the Ready 2 Rumble series.
Serious boxing (simulation) fans as usual dont have much choice. Lucky for them Knockout Kings 2001 isnt that bad in terms of gameplay, and the roster of boxers is simply to die for. Theres still plenty of room for improvement in the series and many will probably wish EA Sports took the game much further than a few scant modes and options.
Fans of Street Fighter 2-style competitive fighters will probably want to stay away from this one. The action is rather slow paced and requires a great deal of patience.
