I am doing a solo playtest to hit rules questions prior to rolling this out to my friends next weekend.
Because the Spring 40 chit 0 was drawn first, the Germans just rolled into Holland and Belgium. This of course, left all the Allied Chit Draws for them to counter with, and they rolled right up into Belgium to meet them.
In the Battle of Flanders, the Belgium troops could not hold out long enough, and the massive French and English reinforcements did not arrive in time.
In the Ardennes, the Germans did not bring quite enough firepower, and the Belgium troops held out better. Because of a little problem the the Home Fleet rushing out to defend Norway, portions of the Luftwaffe were busy. The battle for the Ardennes ended with both sides losing all their Front Line troops in the same round, which if I remember correctly, is a victory for the defender. Funny, the French Airforce (1 bomber and 3 fighters) may have decisive there. Funny that...
