The Xbox Live Creators Program makes it easy for independent developers to ship their games on Xbox One using the social features of Xbox Live - just create a Dev Center account, build a Live-enabled UWP game with GameMaker Studio 2 UWP, and you're ready to launch on the Xbox One to the full Xbox audience.
This is the easiest and most cost-effective way to bring your games to console. GameMaker Studio 2 is the easiest game development tool to learn, and the UWP licence lets you ship your games to Xbox One and Windows 10 environments at a fraction of the cost and complexity of traditional routes to console publishing.
