Personally, what I like in a WW2 game (strategic or operational) is to compare my pace to the historical pace of operations. I have seen that some players have succeeded to do Poland in one turn i.e. two weeks. But in any case two turns, as historical, seems to be the norm.
Now, the "strange defeat" that is always hard to do at the same pace than historically. Fall Gelb has started on May 10th 1940. The sea was reached by German 19th corps on May 20th 1940. So in term of game turns, this is one turn. Anyone was able to do this in one single turn? I bet none was able to do it.
The main reason from my point of view: no stacking. Design decision, understood.
The French strategy was an 'all or nothing' gamble that leds the allies armies to rush for the Germans in Belgium. As such, there was no strategic reserve behind the front line. Funny enough, this cannot occur within this game since the Belgium army prevents the French and the BEF to enter in Belgium. So, the strategic reserve is intact. The AI is safe.
In order for one player to achieve this pace in this game, does one week turn instead of two would have done the trick?
It's an open question, do not see any criticism of the game.
