Definitely missed the summer of XBLA games mentioned above, particularly Castle Crashers, Braid, Geometry Wars 2, and Bionic Commando: Rearmed (unless you already have it for PS3). Duke Nukem 3D just released today, too.
Also, if you pre-order Banjo, you the N64 original for free on XBLA.
Did you by any chance luck out and get a LBP beta key? You're going to be swamped with games starting in October!!!
