I have a few questions which I can’t find the answers to anywhere:
Firstly, what do cities do?
And secondly, what do the different fighting types (random, static, progressive) work?
Well cities currently house possible revolts and cores provide places to move capital in case it is taken. I would like to make them more useful in future. As for combat efficiency setting. If you are on PC it will tell you in a tooltip what they mean. But basically with random CE is randomized every 10 years, progressive changes it to random direction by 1 every 10 years. Static is if you want to specifically set each nations efficiency yourself
