How much does XNA Game Studio Express cost? Is there a difference between Windows and Xbox 360 development?
Visual C# Express, the XNA Game Studio Express tools and runtime environment for Windows are all FREE. To develop, debug and/or play games on the Xbox 360, however, you must have an XNA Creators Club subscription purchased directly from the Xbox Live Marketplace. Two subscription options are available: $99 per year or $49 per four months.
