(Microsoft Image) The company behind one of the most popular game development toolsets has entered into an agreement to use Microsoft Azure as its official cloud partner. Unity Technologies, headquartered in San Francisco with offices in Vancouver, B.C. and Bellevue, Wash., is best-known for its eponymous licensed game engine. Since 2008, Unity has been a popular choice for hobbyist, amateur, and professional game development. While it’s not the loudest announcement coming out of Microsoft’s games division, the company has made a lot of bets, both over the Xbox project’s history and in recent months, that are aimed at expanding the overall accessibility of development.
