I was thinking of this but it would be rather interesting if the next Elder Scrolls game could access previous game saves and customize the path of quests available to you based on decisions you made in Skyrim, like whether or not you killed Motierre for the Emperor or let him live.
So it's kinda like what Mass Effect does. I would like that to happen with the next game. That way the choosies you made actually impact something. So it's cause and consequences which is something the Elder Scrolls is lacking.
