Audiosurf.

Wizorb or Wrath of the Lamb DLC

Fortix

cavestory+

For me it would be Eufloria.
It always seems to elude me when money comes in and games are released. :)

Half Life : Opposing Force.
I wanted to play this game since it came out, but I didn't find it ANYWHERE. Isohunt, pirate bay, everything. Now I am waiting to my birthday..

Gunstar Heroes, both Oddworld games and Dinner Date. All less than $3.

Sonic CD

I'd like Cave Story+.

Max Payne 3

The Graduation Bundle

Game: Blackwell Deception

Dlc: PC Gamer Episode 6

According to my wishlist: Wizorb

Bastion
