You can add more more game that's now available via Valve's Steam download service. Funcom's fantasy MMO Age of Conan has now joined the growing line up of titles on Steam. As usual with introducing a new game, Steam is offering a 10 percent off sale for anyone purchasing Age of Conan before Sept. 11.

Funcom recently announced plans for a commercial expansion pack for Age of Conan that will be released in 2009; they will also continue to expand the game with free content updates for its subscribers. They also plan to release a DirectX10 graphics patch for Age of Conan that should improve the title's visuals greatly. The big question: will the release later this month of Warhammer Online affect Age of Conan's subscriber base?
