I've been playing for some time and I tried both Dictatorship and Republic politics, I was wondering is there a way to make culture victory possible while playing these two politics, because the rainbow disappears when playing dictatorship especially. sometimes when you play in war conditions, you need a large army to defend oneself or allies, but it's not always possible to feed such a large army except when you play dictatorship or monarchy, if your towns are close enough, so is there a possibility to make the culture only affects domain, without affecting the rainbow?
