First, I don't know any thing in making maps, and working with the Battlecraft. But I think many maps in the Clost Combat Series (from A bridge too far to Nomandy Invasion) will be cool if made into FG or BF maps. They are well created maps, maybe not for planes, but I think BF mappers can put in airfields without problem. Secondly, I wish there could be a map with trains. It'll be okey even if the train isn't drivable.
I thought of the same series of games for a map layout, and I am taking it a step farther to learn how to use battlecraft in conjunction with Close Combat, Battle of the Bulge
