An entire province is not doable in an expansion but, as explained in another thread, something like west Morrowind ( https://images.nonexiste.net/popular/wp-content/uploads/2011/12/DLC-Hopes-and-dreams-BLACKLIGHT.jpeg ) or Orsinium (located between high rock, Hammerfell and Skyrim) seems okay for an expansion: we'll visit new lands without having to introduce a 'deux-ex machina' island like Solstheim.
The problems with adding even a little part of Morrowind are many, how are you going to explain the border? What happened to the great houses? what happened to the Temple? Can you still join them? What is the legion presence? How are the Daedra being worshipped now? How are the nine doing? Or is it the eight? Who is the King? Is there still a King? Have they returned to Dukes? Is there an Imperial governor? What Houses are still around? Can you join those houses? How about the College of Whisperers or the Synod? Do they have a presence? Any NPC's from Morrowind (the game) still in that area?
The events that happened in the last 200 years have the potential of completely redefining Morrowinds Culture, command structure and everything that goes with it. This is not something you just add in a little expansion, this would be an entire new game or hugely disapointing. I don't want to see Morrowind rushed like that.
What about new areas, I would prefer new areas to visit. We have already been to the other areas it would be better to see those worlds realized again in a brand new game where things have changed in that world.
Reread what I said Arena takes place on the entire continent in that game you could go to any province you might be able to go to a province we have already been to. Understand now?
I understood, I just think it's a weak argument. Arena is a completely different game from every installment that came after. It's unfair to really compare anything that happened in there to more recent games.
