Steam launches 'Community Market' where players can buy and sell in-game items with real money. The 'Community Market' supports Team Fortress 2's consumable items only for now but Valve promises it will be available with other games next year.You can show off your items on the Community and sell or trade them to other Steam users. According to a FAQ, all sales are final. Steam keeps a 15% transaction fee during the beta period, which may increase in the future. During the beta, sales are restricted to 200 per calendar year, starting with January 1. Presumably you won't reach 200 before then.
Blizzard's real-money auction house for Diablo III has already been successful and proved that there's a scope for it in the future.
