Gamasutra is reporting that Valve's PC game download service Steam has reached 13 million users. The company's offering has 150 movies and games on offer. "Looking further at its stats, Valve says Steam sees over 7 billion player minutes a month, and has served over 2,500 updates to its titles since its first release. Valve also says that summer will see new announcements from more publishers bringing their games to Steam ... Said Valve president Gabe Newell, 'We've approached the development of Steam the same way we treat our online games; we release something we've tested, we internalize the feedback, and then we release new features and functionality based upon the feedback received. In the past year, we've added over 100 new titles from third parties ... This growth has taught us a lot and inspired many additional features and services that we'll be releasing later this year.'"
