F 40 Gold question

[Steel God]

When designing an historical campaign, the historical outcome is the benchmark the designer is obliged to shoot for.  If they don't then they have created a poor simulation.  The historical outcome must be achievable else the designer be blasted for it.  Towards that end the designers use the features that the engine provides, such as unit quality, to make an army last longer or less than nominal so that historical results can be achieved.  It doesn't mean that an average French Infantryman is more or less than his German counterpart in 1940, but historically on the campaign level he performed below standard, how else can that be achieved?  It's easier to design hypothetical games (like Modern Campaigns) but historical battles will wear a designer out because if he misses the history he'll be crucified, if he makes it perfectly balanced he'll be crucified.  So they do what they must, design to repeat history and adjust the scores for "victory conditions".
