Well, IB titles actually look like the DBZ Budokai series of games, but with rective controls rather than the beat-em-up nature of DBZ. Oh yeah... The Superman game is a less stellar version of IB, but has a lot more going on to it that's akin to those of the Budokai series. As for fighting games, i'd recommend Kinetic Damage. I dont think there's anything even remotely close to the old SNES DBZ fighting games.
Thanks for the help, although I know these games existed already Do you think there are any similar to the console ones, where you can fly around the map, use Kai attacks, and use a variety of combos?
