The Caribbean, in the turbulent 17th Century. The mighty kingdoms of Spain, England, France and the Netherlands fight over the colonies. And there you are, a young sea captain whose only goal is to become the most powerful man in the New World. To achieve that goal, you may choose one of the two available campaigns: will you become an Adventurer or a Trader?
Hope it helps someone.
