I would love to play a Morrowind successor with a modern engine, maybe not a total remake, but further along in the storyline of Tamriel. I just want to revisit a lot of those places I used to go to with the same type of rich detail of Skyrim and Oblivion (for its time).
Aside: I would love to see the other regions in Nirn someday as well. We've yet to see anything beyond Tamriel in the modern games, and there are even other races / species we have yet seen which could make for a really interesting game if done correctly.
If they do a Morrowind Sequel or Prequel they need to be careful not to overlook even minor details, unless they go far enough forward / backward to where most things are ignored, but I would say even check the books and the quests of the game to make sure nothing is amiss.
I suppose the problem is that it seems like Bethesda is more interested in creating a sandbox then having a story that fits that sandbox. Going back to Morrowind doesn't accomplish that necessarily.
On the story front I think what it did well was have the lore tie into weird things about the game world. The sand storm, the blight, the floating rock are things that dagoth did on purpose. Likewise, vivec and company are "Gods", that you can meet, but they're also Dunmer who used artifacts to become immortal who knew you in a past life. The visuals are more tangible because the story is integrated into what you see.
Morrowind has a some interesting lore but is the textbook definition of a 'fetch quest' game. I'm not sure I can even remember the plot of any of the missions. Their modern games, while often hackneyed in the writing dept are at least diverting to your attention. "Wouldn't it be cool if a mage dropped from the sky" is probably the high bar of Morrowind narrative chops.
Bethesda is culturally a "level design developer" imo. Kind of like Valve in that regard. They have a technical idea of what they want the player to experience, not a strong narrative one. New Vegas is so interesting because Obsidian clearly do not have the same culture, it was ALL traditional RPG storytelling (and some okayish levels) in the same Bethesda framework.
They did in Elder Scrolls Online. I didn't play that much of it but it's from an earlier time period than in the normal TES Morrowind. It was fun for the sightseeing at least.
The problem with ESO is it's moreso an MMO and less like playing any TES game. I have played it a little bit but its not as immersive as regular TES games feel.
