Xbox Game Studios, previously known as Microsoft Studios, Microsoft Game Studios, and Microsoft Games, is a wholly owned subsidiary of Microsoft Corp. which develops and publishes video games for Windows based PCs and the Xbox video game consoles. It was established in March 2000, spun out from an internal Games Group, for the development and publishing of video games for Microsoft Windows. It has since expanded to include games and other interactive entertainment for the namesake Xbox platforms and mobile platforms. It is the publisher of the entire Age of Empires series.
The studio rebranded itself on February 5, 2019 as Xbox Game Studios, as to reflect Microsoft's intent to use the Xbox brand to support gaming across all the devices it supports. At E3 2019, Xbox Game Studios announced it had established a new internal studio dedicated to Age of Empires.
