Over at the education site Game Career Guide, they've got an in-depth primer of Microsoft's XNA, including interviews with Julie Ellen and Joe Nalewabau of Microsoft about the PC and Xbox 360 indie/student homebrew construction tool, as well as chats with two developers (Benjamin Nitschke and Alex Okafor) who have worked with XNA to some notable effect. Microsoft's Ellie claims of the efforts: 'Homebrew and independent developers are often very talented and have lots of creative ideas. Being able to officially write games directly for a retail console right at home is a first and could be very empowering for them. For the homebrew and indie scene to succeed we need to provide two things: great tools and access to a large audience. We're working on both.'
