Yeah- we've had this thread before I'm sure- but it's been awhile and it's time for a refresher course. I'm looking for suggestions on good multiplayer games- whether it be co op or competitive. Any and every suggestion is appreciated! Looking for mostly "local/socail/ even hotseat" style games (I.e. if it takes 1 console per FPS player- it might not be a good fit here- but it's worth a shot anyways
