Am I a man or am I a muppet? If I'm a muppet then I'm a very manly muppet!
Great review, Tom. I completely agree that the book takes Memoir to the next level. Now there is a reason to fight for every last medal, even when you know you're going to lose the battle. It adds to the tension and fun; with the book Memoir is my all-time favorite game.
You mentioned something really important - the campaign system rewards you for objectives - which means that you have an extra incentive to pursue the historical reasons for the battle as well as trying to plow under the troops of your opponent. A nice touch that moves the game ever so slightly in a wargamer-y direction.
