Steam News announces the latest of what seem like regular weekly sales, saying they are offering all id Software Games for 50% off. This offer ends September 8. In other news for bargain hunters, Steam is also now offering sales of Age of Conan: Hyborian Adventures, offering Funcom's MMORPG for 10% off until September 11. Finally, Steam News announces they are taking preorders for the Steam edition of S.T.A.L.K.E.R.: Clear Sky, offering 10% off of purchases before the release date of September 15. This has caused some consternation on the Steam forums, as the game supposed to be available for online purchase when it arrived in stores (story). Thanks theyarecomingforyou.
