Microsoft, are you trying to mess up your console?!?!
Independent developers cannot self-publish their own games on Xbox Live Arcade. Instead, they must get a publishing deal--either with Microsoft Game Studios or with a third-party partner. Games published on Xbox Live Indie Games are exempt from that policy, but that marketplace isn't necessary seen as viable.
Limitations imposed by Microsoft have prevented a number of games from ever appearing on Xbox 360. And apparently, Xbox One won't change how Microsoft approaches indie games.
When asked if developers will still need a publisher to get content onto Xbox Live, Matt Booty, general manager of Redmond Game Studios and Platforms, told us that "as of right now, yes. We intend to continue to court developers in the ways that we have."
He did add that "I would also expect that for this new generation, that we're going to continue to explore new business models and new ways of surfacing content. But Microsoft Studios is a publisher that works with a wide range of partners, as do a lot of other people, to bring digital content to the box."
When it comes to self-publishing, Microsoft is the odd man out. Both Sony and Nintendo allow developers to publish their own games onto PlayStation Network and Nintendo Network, respectively. Microsoft's position stands in stark contrast to Sony, which has been aggressivelypursuing indie content for PS4.
