I wonder if they are going to include Hunt Valley as an American City again, like they did in Civ III.
On a somewhat related note, I remember when Civ 3 came out, I was working at EB. One of my coworkers was looking through the strategy guide and noticed that all of the cities in the screen shots were areas around the Baltimore area. Dundalk, Towson, Perry Hall, Essex, etc. The store I worked at was in White Marsh, right next to Perry Hall. It was kind of funny seeing that, and we realized that the writer of the guide had to be from the area. Of course, it didn't occur to me, and I never bothered to look it up at the time (or else I surely would have sent in a resume), that Firaxis was located in Hunt Valley.
