you basically have everything
do you have eternal sonata on ps3 already? if you dont then get it on 360!
okay
Kameo - this was decent but not as good as starfox adventure's or Donky 64 in my opinion
viva pinata - have not played this and dont really want to but hey, it's an exclusive
banjo kaazooie nuts and bolts - have not played this either and not interested but it's exclusive
magna carta 2 - look's pretty decent
left 4 dead - ONLY GET THIS FOR THE ONLINE but im not sure if people still play this
splinter cell conviction - have not played this but it look's good
that's pretty much it
