I would like to request a mod that causes rebellions within an empire at certain unhappiness levels.
When i say rebellion I mean, a city or group of cities breaking of from a player or AI civ and forming their own civilization/"country".
Such as your empire reaches a certain state of unhappiness or you drop a policy branch altogether, such as when it causes anarchy. (say you have liberty but want autocracy? Well you drop liberty, go into anarchy, return to a stable government with the new policy branch adopted, and a few turns later a city or group of cities is unhappy with the reform of government and decides to form a new nation/civ from yours.)
You can decide to peacfully let the designated cities leave the nation to become an AI civ/new nation. Or you can decide to suppress the revolution/rebellion and depending on the size of the cities that are seceding a few units are generated for the new AI/Civ and you must fight to retake your cities tha have attempte to secede. (When cities secede or are retaken there is minimal/no loss of buildings)
I may have missed a few key points because im half awake, but if anyone gets the general idea and is interested in making this mod that would be awesome. And feel free to refine/correct any issues with the idea.
