TheViking said:What I had in mind was to reduce the size of the cities to 1 (either using spies to poison the water supply or by attacking cities without walls) before capturing them. In that case capturing the cities destroys them.
This is rather important for me to know because I now have 8 cities and have already destroyed one enemy city which was in the middle of my empire and thus interfered with my plans.
Razed cities would count towards the total number of cities.
