I'm glad the Spanish look like the winners in the latest poll for next faction, better than my initial thought of Austria (it has all these colorful units but no navy to speak of during the NW), and they were both French and Coalition allies at different times. Not to be chauvinistic or anything but there are a number of reasons an American faction might be high up in the pipeline: 1. There seem to be a growing number of Yanks who are playing this game (NA?). 2. The settings and some of the unit classes really would be very different from European (wilderness, wilderness, and more wilderness, but also Louisiana bayou, east coast estuaries like the Chesapeake Bay, Great Lakes, oh and did I mention wilderness?) 3. But some of the most colorful unit classes weren't even mention by Sgt Moon's admirable list like frontiersmen, Native Americans (Indians, all diferent distinctive tribes), Cheasapeake flotilla men, and all flavors of militia from abysmally awful to well-dressed indistinguishable from regulars and good fighters. 4. Some unique weapons would include the Pennsylvannia (or Kentucky, depending on where you're from) long rifle, and other types peculiar to the American frontier like tomahawks, warclubs, etc.
I once had a Brit at a tabletop miniatures con tell me he liked the American War (or "War of 1812" on this side of the Puddle) because it was "Napoleonics with Indians". I would also echo all the other excellent points Moon has made on this topic as well. Some things may not on a poll because most people aren't even aware of this conflict. Many Americans still aren't, but to most Canadians it seems to be a source of pride and they are the biggest promoters of its history. It was Canadian militia and loyalist regulars that did most of the fighting on the Brit side. Just propose it and get the community to think outside the box on this one.
