On top of offering networking compatibility with other gaming platforms, Microsoft had another treat for developers at GDC this week: An easy way to create their own game tournaments with Xbox Live. Think of it as an evolution of Xbox Live's multiplayer matchmaking. The aptly titled Xbox Live Tournament Platform, which will support both Xbox One and Windows 10, is clearly meant to make Microsoft an even bigger player in the burgeoning esports market. To that end, it's also teaming up with esports companies FaceIT and ESL, who will use the platform for upcoming tournaments. The first titles to support the tournament platform should arrive by the end of the year.
