Sandbox building game Folk Tale is looking rather promising. This promise comes from it being a rather pleasing-looking cartoon fantasy game of peasant-management in an early stage of development. That won't stop you from getting your hands on it, of course, because it's over on Early Access, where you can get the game's in-development version in exchange for precious gold of varied currencies. There's a dynamic story system which apparently accommodates your decisions about how to rule your peasants as you knock them into an empire.
