I came in here to specifically recommend Fallout Shelter, and actually its TES counterpart: Castles.
I only played a little bit (cause I knew it would suck me in) but it's pretty much exactly Shelter but with Elder Scrolls stuff. You can have different people join your town and fulfill different jobs like tailoring, blacksmith, crafting and such. You can decorate individual rooms with themes, and I think even furniture pieces. You can create lineages and rivalries between characters. I think the tutorial usually has you make a decision that will lead to something like that (like the first king has an affair with a khajiit woman even though he has a wife and child, who's next in line for the throne) but you can make someone else king if you want.
My mom watched the whole thing in like a day. It seemed enjoyable, but it was weird that it's only 8 episodes and each was only 20-ish minutes.
