Most of the stuff with buildings and so on is going away, actually. It just felt too disconnected. We may have some lists of buildings or something that is nonvisual, but at this point I doubt we'll even do that.
Instead, a lot of it is going to be focused on helping your NPCs themselves grow, and using them for strategic purposes through some new Guardian Powers that will be coming very soon. And we're also going to be having it so that players can wield a lot more direct control over the world map in some ways, come to that; being able to place wind shelters wherever you want (but at some cost, so you want to make each one count), and some other things.
It's a narrowing of focus in some ways, trying to go deeper with what was working well about the game while at the same time keeping to the spirit of some of the disparate components that were previously in there.
