It looks like Epic is adding another tool into the now ginormous Unreal Engine 3 toolbox as they are now including GameSpy`s suite of online technologies into the game. This will allow developers to have access to those technologies while they are building their games. I`m not really sure this impacts anyone outside of PC developers as the 360 and PS3 already have a lot of those features baked in (well the PS3 not quite so much). Still it`s another added goodie that may help sway a developer to pick the UE3 engine over others. This is the third big addition joining the Ageia PhysX engine and Microsoft`s Xbox LIVE service.
