From the early goings, KK2000 has a lot working against it. Primitive looking models, mediocre motion capture, and poor collision detection all seemed to spell doom for KK2000. Trying to draw comparisons with it and what many consider to be Dreamcast's first killer app, Ready 2 Rumble, is more like hitting a man when he's already down. Dale also emphasized the unforgivable crime of using the likes of legendary fighters like Ali, Frazier, and Holmes more for a special effects rouser than a realistic simulator.
Funny thing is, success in the gameplay department had less with actual boxing (that is, good footwork while throwing and blocking combination punches), but more to do with the quirky timing of attacks (like a Street Fighter-style fight game) where most of the time, the opponents walked into my blows. Fighters usually exchanged a ridiculous amount of punches per confrontation as well. Yet, there is a method to the madness and to understand the unique tactics and conquer it gives the player some level of joy. I even ended up going the distance and beating the champs of two different weight classes. Perhaps it was the thrill of the competition or the joy climbing the ranks with my own custom boxer. So while I can't wholeheartedly recommend KK2000 with all its problems (especially to those looking for a serious boxing simulator), I can say that the game gained my sympathies and I managed to enjoy playing it on some level.
