Build your own Games from Microsoft

Microsoft on Monday launched new software and an accompanying service that will let aspiring game developers create games and post them to share with one another. The XNA Game Studio Express software is available to anyone with a Windows XP-based PC. The company's new XNA Creators Club -- available for $49 for a four-month subscription or $99 annually -- provides amateur developers on the Xbox 360 with access to thousands of game assets, white papers, starter kits and technical product support. Microsoft also announced details of its "Dream-Build-Play" contest, which will publish the best amateur-developed game titles on the Xbox Live Arcade service.
