I think it'd be nice to see references from all past elderscrolls games in the next one.
Yeah, would be nice to find an old story teller who knows something about everything. Maybe just vague little references, or not-quite-right 'facts' you would know to correct if you've played the games. There has been hundreds of years, after all, memories fade and vocal lore and legends get twisted.
Also, I would like people to contradict each others, that's what happens in real life. People's opinions affecting the 'facts' they tell you. Nicely done in the Price of Neutrality adventure of The Witcher Enhanced Edition: you had abolutely no idea which side was telling the truth, or was
closer to the truth. And following your gut-feeling hardly led to a happy ending. Lovely game design, just lovely.
