I didn't notice this topic existed. I would have posted since the beginning.
I loaded up on Recettear, The Witcher, Mass Effect 2, Torchlight, Audiosurf, Brink (some friends I know bought it), Borderlands, Psychonauts, Alice, Rock of Ages (might as well, looks lol), Beat Hazard, and Sequence. That increases my backlog to a whole 66 unplayed games out of 99 total.
If you like rhythm games like ITG or play some Stepmania you'll probably like Sequence. I know a rhythm game fan who liked Sequence, so its probably good.
Also anyone here who doesn't have FEAR 1 needs to get it. That game is godlike. 15GB download though.
Edit: Anyone who still wants Sanic go on
Amazon. $10 there and you'll get 60FPS on the PC as opposed to 30FPS console.
