If you havn't played it already, Crackdown is an awesome game (but I think 2 player only?) Same with Earth Defense Force 2017. Any of the Viva Pinatas surprisingly double as fun drinking games. Gears of War 2 has an awesome local "horde" match that you can play - even casual FPS fans dig this mode as it is all teamwork and vs a computer. If you can download it, Age of Booty is a fun multiplayer game as is Aegis Wing and Geometry Wars Retro Evolved. Those are just a few I can think of off the top of my head that can be highly entertaining with friends and/or solo.
