This game is looking really, really sweet and like it'll live up to what they established in Bioshock.
Furthermore, Steam is making it incredibly tempting to buy at the moment what with offering Bioshock and X-COM as pre-purchase prizes... I think I'm going to commit to that... I want X-COM so very badly... and original Bioshock would be awesome too, since I've never owned it, only borrowed. It's a great story and I wanna' go through it again with my gal in tow, cringing all the way haha :D
