Depends how you define cities.
There are 3 ports, if you have access to a ship. There's 1 castle. and 3 taverns.
do you plan to add more structures? for example: temples, other castles from other "kingdoms?", bandit outpost?. a map update?
Yeah I plan on expanding the map in every direction. I have plans for more castles, graveyards and a couple more villages similar to the existing ones.
more islands as well.
