For a second Imperial campaign I'm making starting in 14 AD, I want to make all of Gaul, Hispania, Italy (except one province, not sure which one yet, for the senate), Greece, Turkey, North Africa, etc.. for the Julii...but whenever I try to do it, I can never start the game.

Can someone help me, perhaps typing it up for me so I can see what I need to do? Also, what do I have to do to implement Roman legionary cohorts into the game?
