Nice looking game and a very thorough and readable report - if a bit long.
As to the rules, played them once many years ago and watched them play recently - the newer version. Yes, they play - but much too slowly and 'wonky' for my tastes. I used to play Johnny Reb Two and abandoned it as too complex. I've settled on Rank and File because they are just easier and faster and puts the focus on the table rather than the rulebook. Have yet to try the full ACW option for Rank and File but the basic rules play fine.
Again, very nice looking game. Surprised no other comments yet.
