I downloaded World of Goo about two weeks ago. I finished it last weekend, except for three or four stages I had to skip because they were driving me TEH CRAZI. I wish it was longer. I hope for some form of downloadable levels in the future, or a full-fledged disk release with a couple hundred stages. Wildly inventive, unique, atmospheric, and addictive. Although it's terribly depressing to watch several minutes of hard work collapse and fail--often so slowly that it's painful to view.
Other than that, I recently also bought Sonic 2 for the Genesis at a Pawn Shop, and got Left 4 Dead as an early birthday present.
