I do agree that Daggerfall is in far more need of a remake than any other TES game... Though that'd be... Really difficult with Daggerfall being so huge.
Morrowind lore/culture+Oblivion magic+Fallout 4 crafting+Oblivion magic... Well that'd be an interesting TES game. A certain percentage of people, and I think a very very small percentage, think nothing of value was lost after Morrowind, though I'm personally pretty sure that a ton of good features and mechanisms were removed after Morrowind. Morrowind's factions, environmental diversity, architecture, story, cultures, lore, and art design were all phenomenal. A lot of the things that made Morrowind shine were sacrificed in later games.
I did like the Falmer, and their caves, I think that was a step in the right direction, they are legitimately interesting, same for the Chaurus. But what we really need imo, is more factions, more unusual buildings, and more diverse environments... And hopefully a better magic system than Skyrim's. Skyrim had more of the good things Morrowind had than Oblivion I think... But there's still a lot missing.
Well probably not until they run entirely out of ideas I suppose. It would be a bit early for that.
