What do you think would work better has as model if this was ever made into a game, Age of Empires 3, Rise of Nation, Civ 5 or Total War?

Either EU4 or CK2. Both would work good. 

I've always said that Europa Universalis is to Crusader Kings what SimCity is to Sims. 

Though personally I prefer EU4.
