I'm probably gonna get Super Stardust HD and LittleBigPlanet. I have Wipeout HD (not Fury though) but I barely play it. Don't get me wrong, Wipeout HD is a great game, but extremely challenging. I've already got inFamous as well.
I guess for the PSP I'll get Pursuit Force and either LBP or ModNation, since I have Killzone Liberation.
Hurray for free stuff, but this expands my backlog significantly, especially since I just picked up Portal 2 (still shrink wrapped) and I'm getting LA Noire tomorrow as well.
