I have a spare S.T.A.L.K.E.R: Call of Pripyat and Survivalist Steam key (from the latest Bundle Stars bundle - you can buy it here
if you're interested in what else is in it).
But if you aren't interested in any of the other games and are
interested in the keys I have, feel free to make me an offer.
I'm kind of looking for GOG games (up for suggestion - also not looking for an unfair trade), or any sort of strategy game (Steam, if not GOG).
I've successfully traded with these people
