The key has already been used..

Too bad I already own Crystal City, which wouldn't exactly do yourself no good anyway, cuz you see if I mark this GA as gotten, and SG does an account check for me (they seem to do them every few months), I get banned for like 3 days for not having the game I won in my steam account. So I still wouldn't have marked this as gotten even if I didn't have Crystal City.

So basically, if you are gunna giveaway games here; you either better be able to come up with replacement keys for what you GA; or be lucky enough to get some moron to win who'll mark it has gotten for any game; or live with the fact you could get lots of not gotten marks on your SG account, which I believe does nothing bad either way.

you can steam gift the games, the key thing was added some months ago for ease since most GA's are for keys
