ZOS hear me out...
your character becomes a lord/king/jarl/count of a town or city-state or something.
you win over the town through some quest line and then you become the city or town's leader. in the town you can can customize the city with construction to an extent, and your very own home at the center or hilltop.
I believe it would add a great deal to the RPG side of things and add greater depth to the overall gaming experience.
