[H] GamersGate + Desura Games [W] Steam offers

I have the following Desura and Gamersgate game keys. I am looking for any Steam game I do not own, tradable Steam games or something in the lines of trading cards or TF2 keys. Feel free to post your offers. I have no problem with doing 2:1 or even 3:1 trades. I'll trade 4 of these keys for 1 TF2 key. I'm always open to offers.
