For a more narrative campaign, there’s the new Road to Independence mode, which chronicles the founding of the British colony in Jamestown through to the French-Indian war and finally the American War of Independence.

I don‘t know how this plays out. Jamestown was founded in 1607and the American Revolutionary War (1775–1783), but in a game it could go longer I would suppose. Also, I am not saying that CA sees it this way but the War of 1812 was seen by many as the Second American War of Independence. Could this be where the 1820 comes in???

Depending on how closely the campaign is scripted this could be loads of fun all on its own.
