Summary: First of all, I'll try to keep this review short and simple. I own 2 boxing games for the xbox. Fight Night 2004 and Knockout Kings 2002. Fight Night 2004 has slightly better gtaphics and seems to be a "deeper" game, but Knockout Kings 2002 is funner and more playable.
Summary: I was happy to see some new faces in the game (Klitschko Bros) but like others have stated, it is not strategic and lacks the "boxing" of Knockout Kings 2001. It is true to say that every fight is like a slugfest and the one that can hit the buttons the fastest wins.
Summary: This has pretty much all the champs, Ali, Frazier, Leonard, Lewis, and Holyfield, among others. The graphics, sound, play controls are all well put together. I especially like the blood and bruise feature you can give to a boxer after your player has given him a particularly brutal beating.
Summary: The game has good graphics and fight sequences. The boxer's facial features and expressions when they get hit is realistic as well, which is one of the reasons why I like this game. Some of its problems is that Muhammad Ali is too strong and too fast.
Summary: No one can call this a boxing sim with a a straight face. It's a arcade button mashers nightmare of the worst kind. How can EA, who is KNOW for making great sports title drop the ball (no pun) on KK2.
