I would like to see a civil war origin in which your empire starts as an advanced empire if not a little bigger than standard advanced. and along with that, I would want the empire to have a host of negative empire modifiers and in-depth situations and events that can determine the outcome of the civil war. Maybe one event line delays the war or speeds it up. Also maybe there could be choices to increase or decrease some "support" mechanic to possible factions in the coming civil war.
