The Caribbean in the 17th Century; You will trade with over 60 towns and create your own production facilities. You will not only increase your trading empire, but you will also have a larger influence on the development of the New World.
Trade is not everything though, as pirates and military fleets threaten your trade convoys. Escort ships for your convoys are needed, or you can turn the tides and hunt for pirates or capture the military ships, becoming more famous and expanding your own fleet as well as your stock of goods.
If that is not enough, you can also take on missions for merchants, diplomats and other characters. With the even more desirable missions of the Vice Kings, where you are to attack and conquer enemy towns, you will be able to influence the defences of your home towns directly. As a sign of gratitude you will be awarded land, to be used later to build and oversee your own towns.
