I'm not sure whether I should change up to democracy. I am Persia in Regent, near the end of industrial with around 2/3 of the territory, the rest shared between 3 civs. I have parity in tech, the largest army and absolute control of the largest continent and a further large island and a share in a smaller one. My problem is corruption. My large continent has a productive end and a very unproductive end (formerly owned by the zulus). Out in the islands nothing much gets buit at all. How can I make my empire more productive? I have roaded, railroaded and improved all the terrain. Everyone is at peace finally. Is it worth changing governemnt to reduce my corruption?
