You take control of a country during the Colonisation age. You will attempt to conquer and colonise whatever you can. Including Australia or if you want to risk freezing to death Antarctica. You may take control of any European empire during the time, Any empire in the Americas, Any of the indigenous people of Australia, A person, a company, Or a rebel group. I don't know if these should have turns or just posts but I do know that if you do play as an empire or company posts will be in the eyes of different people.
