Unfortunately, I have terrible satellite internet so online gaming is a big impossible for me and my 1,000 dollar tower doesn't have enough vidRAM to play any new games at a tolerable pace (looking at you dragon age). I would love to have TF2 and LFD2 for the PC, as they are a blast on the 360. Mostly, on my PC, I have small indie games like VVVVVV, Bit.Trip.Runner, Braid, World of Goo, Machinarium, and my personal fav for PC: Amnesia: The Dark Descent. If you want one of the scariest games that's been released in ages, you need to get it.
And I Should Contemplate this Change, to Ease the Pain. And I Should Step Out of the Rain, Turn Away.
