H: Nuclear Dawn, Terraria, E.Y.E: Divine Cybermancy, tower wars W: Age of booty, worms.

I can offer you a Serious Sam 3 key for E.Y.E. + Tower Wars + some cards (I'm looking for the Football/Kerbal/Prison ones from the summer sale.)

I also have a key for Worms (the original game not one of the newer ones), if you're interested - I'd trade it 1-1 for one of the games I'm interested in.

are interested in Anomaly: Warzone Earth?
