After four weeks in beta form with over one million in-game items and game gifts swapped, Steam trading is now available to the community as a whole. Items range from Cave Johnson’s GOTY, Portal 2, and Sega’s co-op adventure outing, Spiral Knights. To celebrate their own achievement, Valve is putting items on sale from both of those titles as well as the trade-compatible FPS, Team Fortress 2.
