I usually play standards but for a change of pace I started a huge/3 continent/30 civ game. The time between turns isn't too horrible on my PC but the sheer amount of time to move my stacks from one side of the continent to another was excruciating (why isn't movement scaled?). In retrospect I should probably have multiple SoDs. Now I have finally pacified my own continent there are 2 more to go! Funnily enough 1 entire continent had no religion until I made contact.
