Well I also believe that our reviewer is kind of young. Since he can't think of a good any good civil war game.
While there have been plenty of those, like SSI's Gettysburg, Antietam, Chickamauga and Shiloh, Civil War Generals 2, Sid Meier's Gettysburg, The Battleground series (Gettysburg, Antietam, Shiloh, Bull Run) and SSG also had a whole serie about the Civil War
I even can remember one of my first games on the Commodore 64, called Johnny Reb II, it was of course very simplistic but I had hours of fun with it.
He also says that wargames about that war before 1900 must be boring because you only have 3 unit types (Inf, Cav, Art). That is a bit strange since most table top wargames focus on that era
But he gives it 8.5 so that is good, and the game is good. And he is right about the background music, I miss that to.
