I was going to do something similar to this guide, but Spain declared war on me, and the Iroquis declared on the 13 colonies in the early game so decided to make a clean sweep and have spent til 1722 capturing all of the non french territories in North America - the French fleets in Europe are rather large so not ready for that yet for a few turns.
Once the Spanish navy is fully sunk, territories consolidated and all trade routes secure I will either attack frances America colonies or invade the spanish colonies in Europe. I tend to focus on one opponant and wipe him out then move on.
That said the french territories of North America and mission completion that goes with looks oh so tempting....
Which do you guys think would be more beneficial -
Declaring on the french to complete the mission and own all the American Theatre?
Or the capturing of Spains European territories first then France?
