I have no clue what an mmorpg is, but you can see WDW in 3D on Google Earth. It's pretty cool to "walk" the streets in the parks in 3D!
I think it would be pretty cool if Disney made a 3D mmorpg based on their Walt Disney World.
What do you think?
Some fans have made Mods (custom worlds) based on some Disney rides.
