iOS 4 Game Center goes live for developers
Just like XBOX Live or Playstation Network, this service will make adding social gaming much easier for apps developed on the iPhone or iPad. The following is from appleinsider.com:
Game Center is Apple's new social gaming network for the iOS platform, which allows users to login to an account, invite friends to play games, find other users to join into multiplayer games, track achievements within games, and compare scores in leader board listings.
In addition to the new Game Center app, iOS 4 includes a series of GameKit APIs for developers that enable them to add Game Center support to their apps.
