Bioshock is pretty awesome. I'll never tire of it.
As for an old school game? I enjoyed Legacy of Kain: Soul Reaver. Who doesn't love vampires with fat claws? Ooo and I loved Resident Evil. First one of course, I'm not so big on the others.
Like many of the other people here, my prescribed text is Cosi. My related ones are 'Miracle on St. David's Day' and 'Once were Warrior's.' Nothing very exciting... oh well, better than having nothing at all.
