I'm playing a game on Regent, standard map. I put it on random and think it was put on archipelago. I destroyed all of the other civs but one. Also I have conqured almost all of the small island around the map. There are only 2 islands left with the romans on then. How can I tell how much landmass I control so I know if I should just invade the Romans and conqure their cities until I get to 66%, or just wait till the cities on the islands expand more?
