So far, the Ready 2 Rumbles have been the games that I enjoyed the most. I remember renting the first one as a kid and probably putting 20 hours on it in a week, but I forgot how good it was...Then again, maybe I'm just a sucker for boxing games...There was a kickboxing game on PS1 that I rented 3-4 times that I thought was amazing, but I cant remember the name...
