I have a spare copy of Portal on Steam from my Portal 2 pre-order.
Seeing as Portal is one of my favourite games, I'm willing to gift it to any poor soul who has yet to experience its awesomeness. Not looking for anything in return.
Dude.... seriously? If you are just giving it away, I would be MORE than happy to take it. I have heard nothing but good things about it, but haven't had a chance to play it yet.
My name on Steam is roberttitus =)
