Best of the Best Championship Karate is a realistic fighting game. After you choose your fighter for his parameters (strength, stamina and resistance), you can choose from 55 different moves. You can now train your fighter at a gym before the real fights. To master the game, one must alternate training and fights, as training improves stamina, strength and resistance. Be careful, loosing a fight reduces those parameters, so you have to be ready before getting on the ring !

No, it's not karate - actually, it's kickboxing, a hybrid between boxing and karate.

A unique game in the Genesis sports genre. Having no competition is not a bad useridea, since there are no others to either rip you off or show how bad you are. It's decent enough, but it ain't no Street Fighter - nor is it supposed to be.
