With Fallout 4 having a voiced protagonist, Bethesda showed us that they can record mountains of dialogue for a game, so If we apply that to the next ES game, we could have more realistic NPC interactions. What I mean by that is, instead of a max of 20 or so lines for your average NPC, we could see around 100 or more. It'd be really fun to make actual friends(not just random people who come up to you and give you stuff). Ideally, I'd like them to be as close to IRL people as possible, but I know that's next to impossible. After a while playing skyrim of Oblivion, you get used to the cookie cutter lines used by the NPCs. How many times have I heard Adrianne say "Got some good pieces out here if you're looking to buy, more inside!"
What do you think? Could the next game have NPC's with individuality and their own character?
PS: I'm not saying that the previous games did a bad job at immersion, i'm just saying that it would go so much farther
