So you tell me that you play all your campians exactly as history had them? I can understand doing a Roman campian for it, but for the other ones it's impossible. As soon as the sun roes on the first day of 272 BC anything could happen.
So play Macedonia and recreate Alexanders Empire, and then fufill al his deams and concer the med.

Don't just sit around there waiting for the romans to destroy you.
