Banjo Kazooie, Geometry Wars, Castlevania: SOTN (good game but I just personally dislike the series), Cloning Clyde, Marble Blast Ultra, Pac-man C.E., TMNT 1989 Arcade, UNO, Worms, and there are probably a ton of others but I pretty much stopped playing video games a month or so after halo 3 came out...
And honestly I really loved Aegis Wing. It was great 4 player fun and it could get pretty crazy- not to mention it is free...
