World of Goo (Steam gift) for 1 TF2 key if you want it??
I also have both Mafia II and Duke Nukem Forever Collection, however they are both keys. I won't scam you if that's what you are worried about, I have a lot of positive rep on here to back that up.
I don't accept keys, only tradable gifts.
Offers please, don't add me directly without a deal.
