A new game development platform from Microsoft allows anyone to create games for its Xbox 360 console, the company said on Monday.
Typically, console games are designed by large studios that must pay high prices to buy development kits in order to write games for consoles. Microsoft's XNA Game Studio Express is a new development kit, to be released in beta form in August, that will be available for free to anyone using a Windows XP PC. The kit is designed for game developer novices as well as studios, Microsoft said.
Users will have the option of joining a developers group for $99 per year in which they can share and test their games with other designers and access information that could help them speed up the development process.
More than ten universities, including the University of Southern California, Georgia Tech College of Computing and Southern Methodist University Guildhall, will include the new platform in the curricula of their game development schools, according to Microsoft.
