I think the graphics of this map look good, and I think that changing it from "American Revolution" to "The 13 American Colonies" was a good idea. I also think that the removal of Canada was a good idea.
What about basing it off of something like this:
http://www.scarsdaleschools.k12.ny.us/m ... colmap.gif with each colony having a few territories, then getting a bonus for holding each colony? I think that makes more sense than how you have them grouped now for bonuses. The other option would be to just have five bonus regions (one for each of the Colonies group plus the boats) but that may make gameplay too difficult.
A bonus for each colony would be a problem with Rhode Island and Delaware at least, I don't see you splitting them into more than one territory. Maybe make them +1 auto deploy? I don't know if that would make it a problem at the start since I assume someone would drop them. You could always make them neutral to minimize this problem.
Since Vermont was disputed between New Hampshire and New York, how about having that as a territory that gives you a bonus if held in conjunction with either NY or NH? If you hold all NY, NH, and VT the bonus would still just be +1 though.
Also see that Maine was part of Massachusetts at the time, so that may pose a problem, since they did not border each other. Maybe use one of the ships to get between the two instead of having to go through NH.
I like the idea of the Indian Territories as killer neutral shortcuts between some of the colonies. I think the way you have it now with the two Indian Territories is a good idea.
