The format I'm using for the book is similar to the format used in the published campaign settings -- I'm gonna put up the continent's general description, then go into detail about each colony. The published campaign settings tend to have 4 sections: a general overview, notable cities, notable terrain features, and notable people. I will be adding notable colonies between notable terrain features and notable people, using the same format as other cities; that's where I'll address that aspect. Nearly all of the colonies in this setting are still in the individual city stage; so Jamestown, not Virginia.
I'm glad to see people have interest in the colonies, though. The colonies will certainly be the highlight of the campaign setting; I could see most games starting out at a colony and spending the first eight or so levels there, running various tasks for the governor and dealing with neighbors.
