1. On the demographics, what is literecy and approval? 2. I was fighting a civ, and took over all of their citys, but they still have some untis, which I can't find. Is there a way to know where those units are? 3. When a building says "requires 1 coal", will it consume the coal? 4. Will I attack many city-states, will allied city-states get mad at me?
