Mass Effect 1 and 2 obviously.
Alan Wake is a very good game with a fantastic story.
Blue Dragon, Lost Odyssey and Tales of Vesperia for JRPGs (In that order IMO)
Crackdown for endless fun
Call of Duty 2 is a bit old now, but still a very good singleplayer FPS.
Ninja Blade is a good action game
Get a play & charge kit. Other than that I don't think you need any more accessories
