One of the many many flaws of fallout 4 was how it started. The idea of showing the pre-war world and the whole frozen thing? That's fine. That's RIPE with possibility. But the whole SHAAAAAAAAAAUN thing and voiced protag? Fucking christ i did NOT like that. It felt way too limited in how you could roleplay,barring you simply totally ignoring the main quest.
I don't think they'd be foolish enough to do anything like that in the distant future ES game,but I wouldn't wager money on it.
If i were going to create an ES game, I'd probablyset it in either Elsweyr or Hammerfell, and i'd start it out with youseeing a strange series of phantasmagorical lights and images of the desert and moons, then that ends and youfind yourself lying on the ground, surrounded by dunes. you get up and find the remnants of a group of people, all burned to death rather grusomely. You walk over to a nearby oasis and do your character customization as you look into the reflection. At that point you have a few vague clues about who the people around youwere, but you're totally free in the world right after makingyour character. I think having a big, genuine mystery in front of you and the freedom to ignore it is way cooler than a lame on rails exposistion fest.
