I don't play anything on PC/computer. Partially because I have a Mac, but also because I hate the whole installing, adjusting settings, compatibility issues, etc.
Flower is the game where one of the writers of the IGN top 25 PS3 games list talked about it bringing tears to his eyes. Really hard to take it seriously now. Well, not that I ever really could have, with a name like "Flower". I'll look into Trine and BTTF.
LBP? LittleBigPlanet? If I get lucky enough to be included in the Welcome Back thing, I was thinking about grabbing that and Infamous. But I am not going to hold my breath. TLP doesn't really look that interesting to me, but the positive reviews are overwhelming.
I just blew $6 bucks on Resident Evil 2. Totally worth the ability to play the game with a wireless controller without having to get up to insert a disc. I think I now own four copies of that game... N64, GC, PC, and now PS3. Carp.
I definitely appreciate not having to deal with MS points and only being able to spend certain increments of money. Nice being able to pay exactly $5.99 for something that costs $5.99. That along with the ability to copy folders of MP3 files straight onto the hard drive are two places where it really owns the Xbox.
