This is just a what if basically your dream idea of what Daggerfall could be like if you were able to remake it with no limitations. It doesn't even have to be realistic.
For instance having the map be just as big as it is but with graphics and mechanics better than Fallout 4. So you would literally get lost if you went out into the wilderness.
For me the main quest and side quests would be pretty much the same maybe rewriting some of the dialog to make it sound better. But you would still get the timed quests where the NPC would say something like you have 25 days to do this quest or Something along theme lines.
So cities would be just as big as they are now pretty much nothing would be scaled down.
I haven't really played to much off Daggerfall but I just think it would be awesome to see a TES game that big with as good or better graphics and mechanics.
So let me know what you would keep, take out, or redo/improve
P.S...
Yes I know this will never happen I just like to think of what it would be like if it we made today and still be able to be as big
