My little brother has a P.S.3 but its not mine so... I don't count it.
P.S.3 has LittleBigPlanet,LittleBigPlanet 2,Modnation Racers, and Buzz
360 has Banjo-Kazooie Nuts And Bolts, Left 4 Dead 1 and 2, and Alan Wake
Both have Resident Evil 5, and Lost Planet 1 and 2.
That should be it... As you can see their is a decent amount their but not enough for me to want to play my little brothers P.S.3 or buy a 360...but that could change after E.3!
