There has been many discussions in the past as to whether or not SC could reasonably deliver true persistence on a grand scale of 1000 players or more. Here is a working demo of a game with not quite the level of fidelity of SC but is using Unreal engine 4 to allow 1000 players in a persistent world with over 10,000 NPC. Lets put the doubt to bed and envision what SC will be when we have a rich and diverse universe.
