With Steam now giving away games as part of the Holiday Sale, a lot of us are bound to end up with extra copies of games. Instead of letting them sit around our Steam Inventories, let's spread them out among other Gaming members.

Add an answer with the games you're trying to trade, the games you're willing to give away, and/or the games you're looking for. In the comments of other people's answers, propose trades for your own stuff.

Please keep your lists up to date!

Also please list your coupon's usage and expiration dates!
