Graphically, the two games are identical when it comes to the action portion. No improvements were made to the Sega CD version, although, honestly, that's not really a bad thing as the graphics in the Genesis game are good. The backgrounds are specifically well drawn, and the animation of the characters is acceptable. It's just about everything you'd expect from a Batman game, graphically.

Gameplay is where the Genesis game really falls off. The controls are frustrating and just plain not fun. You'll find yourself getting hit by the enemies and not being able to do anything about it because of the poor control. The Sega CD driving game however makes up for the poor control of the regular game. The driving game, although, not "real" driving, is a lot offun, and let's face it, who hasn't wanted to drive the Batmobile at one time or another? I know I have. If I were to pick one of these two versions to be stranded on a desert island with, I'd choose the CD version, though, honestly, neither of these games would be with me, as they certainly aren't the best Batman games made.
