But to be serious, some comments in addition to what 82ndTrooper has written.
First of all: his attack on France is simply brilliant. Sending parachuters in the back of the French army has cost the loss of some production centers.
I was expecting the German army coming from the north, making their way through the Low Countries. Therefore I have placed a lot of units there that I would need in the eastern part of France now. Meanwhile the first armoured units arrived at the front, like those tank units that have encircled the parachuters at Lyon (and now, a turn later than the one that the screenshots above, have eliminated them).
At Maginot line the units in start turn contained 30 rifles, some machineguns, an AT gun and an infantry gun, First I did was to split the units in two groups. One group contained rifles, machineguns and the AT gun. It should hold position at any cost. The second group contained rifles and the infantry gun, as it is more useful in attack than in defence. Some of these units were placed in second line, together with armoured units. Their task was to move quickly to any point were the enemy achieves a breakthrough and drive the enemy back. It did not work as there was no breakthrough but a complete breakdown of the French frontline. The fortifications had cost high losses for the attackers but did not stop them. The river at Nancy is the next defence line now, but it will be outflanked in the south. A third defence line is already build, but as soon as the enemy has brought enough forces in position it will fall.
The main reason why France ont survive long is (beside a very well done attack), that the war footing is still low and the deployment especially of heavy units is not sufficiant. All French HQs start with only half of the necessary staff. Beside supply a lot of staff has to be build as well as PP for increasing war footing. There is not much left for heavy units and those that can be build are weaker than their German counterparts. Only the Panhard is a very effective weapon. Btw, I am producing only those units that were historically present. That means the French fighter squads consist mainly of Potez63. No Hurricans or Spitfires are build in France. As well the British build the Morris scout car although it is not as powerful as the French Panhard. The Potez63 does a quite good job but it is much weaker than the German fighters. The losses of ther German Lutfwaffe aremainly caused by flak than by successful fighter defence.
82ndTrooper has shown some screenshots to demonstrate how drastically the supply is reduced in some areas. But that is not the main problem for me. There are around twelve French HQs and I have connected all supply centers in the south, west and north with nearby HQs. They are not dependent of supply and reinforcements from Paris as well as the HQs at Maginot line have not been. But the loss of production centers due to parachuter attacks decrease the total amount of production and that is what causes problems. Of course I had garrisoned some infantry in most of the cities, despite a different impression that Krupp_88mm has got. But the garrisons were too weak in some places and the enemy taking the bridges disable me to use some mobile units that I had placed in the mid of France. They were meant to move quickly to the places were the enmy might attack with parachuters. So it was not unexpected that this would happen. But I had not expected the number of parachuters that attacked and was simply unable to fight that much of attackers. Putting that much strength in the airborne attack was the best strategy!
At least I want to point out that it is a great scenario and it is really thrilling - so much that I forget again and again to do some screenshots. Sorry for that. But here is one showing the situation from the French view. You can see some tank units north and north-east of Paris, coming down from the border to Belgium where they were placed to defend in case the Germans would move through the Low Countries. The HQs at Nancy (center of map) and Mulhouse (lower right edge) get supply and reinforcements from the local centers. Production centers west of Paris are garrisoned and some fighter squads placed there.
