Epic Games has agreed to incorporate GameSpy's suite of online technology into Unreal Engine 3, under the terms that the technology will be immediately available to any publishers or developers that license the engine. PlayStation 3 and PC online functionality, along with communication tools and competition applications, will also be available to Unreal Engine 3 licensees. Epic has said it is not interested in Microsoft's Xbox Live, particularly with Games for Windows. The Xbox 360 versions of Unreal Engine 3 games will have to adhere to the Xbox Live rules, possibly hinting at Xbox 360 gamers being excluded from cross-platform play.
