Ok, as I understand it, there are a total of four 16-bit Spider-Man and Venom games. There are two versions of Spider-Man & Venom: Maximum Carnage, and there are also two versions of Spider-Man & Venom: Seperation Anxiety. For the Genesis and Super Nintendo respectively. I haven't played any of these games, but I'm trying to find out which game is superior, and which system has the better version of the superior game. My son is really into Venom right now.
