There's a video game apparently coming from Disney called Virtual Magic Kingdom. It's a "persistent world," meaning it never shuts down online. People join up when they want, and leave when they want for the day. The term is MMOG: massive multiplayer online game. Plenty of other companies have this kind of thing already.
But this one will be set in the Magic Kingdom (no word on whether it will be DL or WDW, but I'm betting on Florida).
I just might have to play this one!
