First, they're gonna have to be two-player games. Viewtiful Joe and Prince of Persia aren't. Gauntlet is a safe game where there's violence (killing zombies, dragons, other supernatural evils), but no blood. Soul Caliber is a far more advanced fighting game.There's no blood, but they're graphic methods of taking down one's opponent. Mario Kart is one I also recommend. Two-Player, minimal physical action, all action and racing.
