They're keys from the humble bundle, so you get a URL where there's a button to click to redeem on Steam. You actually seem to have all four of those games! You could take them anyway if you wanted (you can see whether or not they've been redeemed, so it's safe to re-trade). Otherwise I have some other stuff:
Still Life bundle (Steam gift)
Defense Grid: The Awakening (key)
Europa Universalis (key)
Mafia II (key)

PermalinkI already have Zeno clash, but I guess I could take the ship. What would you want in exchange?

Looking for bundle games I don't already have (game list). Wishlist is good but not necessary. Or buy for 2 ref each!
Have: Magicka + 2 DLC, Natural Selection 2
Wishlist: Zeno Clash 2, Eufloria, Audiosurf
