My first suggestion would be to keep it simple. I'm assuming you're basing the RPG off the video game Morrowind, which is super complex and takes months to master. RPGs should be able to be completed within about six hours, unless, of course, you're aiming for a D&D type of ordeal.
Otherwise, I have never played Morrowind so I can't add much else.
Well I would need more than the just Morrowind to really give you any suggestions. However, if it is to take place on Morrowind (duh) then it'd have to be on the mainland or before the events of the game because after that Vvardenfell becomes uninhabitable.
