"Epic Games announced today it has licensed GameSpy's online multiplayer technology with plans to incorporate the software suite into its extremely popular Unreal Engine 3 platform. What may read like a dreadfully boring partnership to some, is actually very good news for PLAYSTATION 3 owners and the PC gamers who want to mop up the floor with them.
Word of warning, though, PC snobs, the PS3 version supports keyboard and mouse controls, too.
The agreement will bring "seamless" PS3 and PC online functionality to games that license UE3, including matchmaking, leaderboards, instant messaging and secure player profiles and stats. Could Epic's own Unreal Tournament III be the first UE3 game to support the GameSpy tech? With UTIII snubbing Games For Windows Live, it's starting to sound like a possibility."
