Hoping to spur interest among video game enthusiasts, creative types and students, Microsoft Corp. said it plans to offer a consumer version of the professional software tools used to create video games for its Xbox 360 console.

The XNA Game Studio Express program, an offshoot of the company's more robust XNA Framework, will be available Aug. 30 for a $99 annual subscription, the company announced Monday.

The software, which requires a Windows PC to operate, will let anyone with the desire create their own video games and then share them on Microsoft's Xbox Live online game service, said Peter Moore, a Microsoft vice president.
