The devices that can run Game Center are iPod Touch 2nd generation and later (iOS 4.1 or higher required); iPhone 3GS and later (iOS 4.1 or higher required); all models of the iPad (iOS 4.2 or higher required); and all Mac computers running OS X 10.8 Mountain Lion or later.〔 ==History== Gaming became a major part of the iOS platform when Apple launched the App Store on July 10, 2008. Unlike the console systems that were currently on the market, Apple had no unified multiplayer and social system for their platform. This gap was soon filled by third parties, such as, OpenFeint, Plus+, AGON Online and Scoreloop. These third parties had control over the online gaming environment and with multiple third parties involved, it left a non-unified experience. Game Center was announced during an iOS 4 preview event hosted by Apple on April 8, 2010. A preview was released to registered Apple developers in August.〔 It was released on September 8, 2010 with iOS 4.1 on iPhone 4, iPhone 3GS and iPod Touch 2nd generation through 4th generation, and is included with iOS 4.2 on the iPad. An updated version of Game Center was released with iOS 5 that featured the addition of turn based gaming, player photos, friend suggestions, and achievement points. The iOS 6 update added Challenges, a way for players to challenge other players to beat leaderboard scores or earn achievements.〔(【引用サイトリンク】title=What's New with Game Center in iOS 6 - Ray Wenderlich )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Game Center」の詳細全文を読む スポンサード リンク
