Valve Software -- maker of the iconic Half-Life series and proprietor of digital storefront Steam -- today released Steam's first non-video game software (originally scheduled to launch in early September). ArtRage Studio Pro, CameraBag 2, GameMaker: Studio, 3D-Coat, 3DMark Vantage, and 3DMark 11 join Valve's own Source Filmmaker in the newly minted software section of the Steam store. All non-Valve software is PC-only for now -- we imagine Mac software will also show up at some point, but nothing's available just yet. Like Steam's games, software titles will receive streamlined updates via the Steam client, and consumers will enjoy similar discount offers to the games section -- the first such sale is already on, with launch day software getting a 10 percent discount until week's end. Bizarrely, the software titles also have Steam achievements. Finally, developers get rewarded for porting their games to Android by something other than crushing piracy!
