Wow, I just managed to encircle a huge force of French, British (BEF) and Belgian troops in Bruuges. I captured Dunkirk first and received two free brigades! Not only that, I also managed to win the battle of France, in less than 30 days and with very low casualties. So I received a light panzer division as bonus. Against the AI, even on aggressive, it is not so difficult anymore. You don't want to aim for Paris first, but instead, encircle as many allied troops in Flanders. Any infantrybattle where your looses exceed 5000 troops, STOP them instantly. Instead only assault with you panzers. Once you destroyed 20-30 allied divisions in Flanders, the rest is easy. Just capture Paris and wait, don't even go south, just wait it out until the armistice sets in.
I really enjoy this mod, thank you! - even managed to hold out as Italy in Cyrenaica, until April of 1941, so almost 9 months of attrition, where my Stukas and the Italian medium bombers have reduced at least 5 allied divisions, mostly South Africans. In my first game with this mod, I had a German casualty rate above 300.000 before April 1941. Now its down to 90.000, and for that I got Poland, France (with Vichy), Netherlands, Luxembourg, Yugoslavia and now, almost Greece. The allied 'AI' just ecleared war on Norway, so I got all these heavy water blueprints for free. Excellent. Love this mod!
