The most challenging maps for you.

I would add that a lot depends on the map. If the map is large and enemies cannot come themselves due to border gates, or border guards (in cases where the author intended only you to be able to cross the border to visit the enemy), then it's possible to start with the capital. But if the map is ordinary, how will you fight enemies without an army, even if you have a billion gold? :confused:
As for playing as Fortress, especially on impossible difficulty: I would like to see that!
I was planning to write about why Fortress is one of my least favorite cities. There’s this topic; I don’t think it has been discussed yet… Here, I wrote it: /topic/8304/
