EDIT: All my keys are gone, but there should still be more in the comments.
I have some brilliant news. I recently acquired the new Humble Indie Bundle 12, mostly for the physical goods that came with it. As such, I am sitting on a pile of keys for games that I already have. If anyone would like to receive one of these keys, comment below and let me know which game you want. This is obviously a first come, first served deal, so act fast.
The keys being given away are:
SteamWorld Dig (claimed)
Gone Home (claimed)
Papers, Please (claimed)
Prison Architect (claimed)
So act friends. If I need more info from you, i.e. we need to be Steam friends or I need to enter an email address, I'll follow up.
EDIT: OK guys, the Steam Key gift is a link. If you want me to just post the link in your comment, I can do that. If not, I can email them to you.
