Microsoft's choice to partner with Facebook is clearly a strategic one that's also related to broadening the appeal of its upcoming xCloud game streaming service and its overall gaming efforts. Microsoft will work closely with Facebook to bring xCloud to Facebook Gaming, allowing viewers to click and immediately play games that people are streaming. It's a vision that's very similar to Google's ambitions with Stadia, but Mixer has lacked the scale and viewership to truly deliver this more broadly. Microsoft recruited exclusive streamers like Ninja and Shroud with big deals, but they haven't been enough to get more people using the service over rivals. Ninja, Shroud, and other top streamers are now free to rejoin Twitch or stream on Facebook Gaming.
