Anyone played Streets of Rage? I have GameTap, and it has the trilogy on Genesis. It's a cool beat-em-up game where an evil crime syndicate takes over a town, so 3 ex-cops decide to go out bash heads to stop the syndicate. It's very challenging, and in the sequels the gameplay changes a lot depending on who you play as. One is a kid with roller-blades, another a gigantic muscle-bound wrestler.
