Budding game creators, your time has come. Microsoft has decided to use Xbox 360 users to make new games. The company says that it will begin selling them later this year on its Xbox Live service for $2.50, $5.00, and $10.00 using MS points. Games are created under its XNA initiative. In order to become a future game star you will have to buy a $99.00 premium membership to the XNA Creators Club, but we figure that’s a small price to pay when those big bucks start rolling in.
