I just wanted to ask if Skywind will feature scale like Skyrim where everything from towns to forests was scaled down compared to TES lore.Will the map be the same size as in original Morrowind or shall it be bigger/smaller?
Also will the towns be bigger and be home to more npcs ?
Also...also ? The final version should not require original Morrowind to run right ?

It will require both,
It will require both, Morrowind and Skyrim whit most DLCs, check the skywind faq for some of these questions:

For the other questions I really don't know.
