Trade Team Fortress 2 hats for other items, full games
Valve introduces Steam Trading.
Don’t let your obsessive hat collecting habit in Team Fortress 2 go to waste. Just join Steam Trading!
Valve has introduced a new trading system that now allows players to trade in Team Fortress 2 hats for other in-game items, or even full, un-played versions of games (currently Left 4 Dead).
The system is currently in Beta but it is open to public participation. To enroll, go to Steam, then Settings and opt into Steam Trading Beta. Now your Steam Community profile will have an item inventory, and will allow you to view item inventories of every public profile in the Steam community. You can then invite people through Group Chat, and also trade with anybody in your Friend’s List who has chosen to opted in.
There is a FAQ up for the “nuts and bolts”.
Hats for free games? Oh yes, please.
