The most interesting part of Microsoft’s Xbox LIVE implementation is the fact that Microsoft is building async multiplayer into the platform. Async multiplayer will allow Windows PCs, Windows Phone and Xbox 360 users to play against each other using multi-player and matchmaking functionality.
Ben-Menahem also revealed that Microsoft plans to open up its developer side of Xbox LIVE for Windows 8 in a weeks time.
Participating for developers will be free of charge and the audience at BUILD on Thursday morning appeared impressed with Microsoft’s work on Xbox LIVE for Windows 8.
The Xbox LIVE service is available in 35 countries today and has around 35 million subscribers.
Xbox LIVE users spend around 2.1 billion hours per month on the service, roughly 60 hours per user per month.
