What a horrible night to have a starving wallet. There's so much stuff on sale I don't know where to begin. o_O Might get Anna to begin with, and I'm also curious about Castlevania: Lords of Shadows and Sleeping Dogs. I'd like to try Resident Evil 6 though I'll probably hate it.
Amnesia: The Dark Descent is 75% off so if you haven't played it yet now is the time to pick it up! There's a 30% discount on the sequel, A Machine for Pigs, also well worth getting. And you have yet another chance to get Alan Wake. Do it or die!
