Apple's social gaming network currently on the iOS will be supported by Mac OS X with the release of Update 10.8 Mountain Lion, according to Edge. Update 10.8 Mountain Lion is a paid update that will be released this summer. Like its iOS counterpart, Game Center on Mac will include support for achievements, scoreboards, online play, game invites and matchmaking, and add cross-platform play and in-game voice chat. Game Center has 100 million registered users, and the App Store features over 20,000 Game Center-enabled games, according to Apple.
It will be interesting to see how Apple makes games playable on iOS devices like iPhone, iPad and iPod Touch, work with games on the Mac, which lack the touch-screen capabilities of those other platforms.
Mac developers have access to a developer build of the new OS today, apparently.
