There are wargames that force a player to play along certain directives, and nothing prevents a WiF player to play with houserules doing the same. If you'd want to recreate the historical feel, you could agree on France having to set up (and stay) behind the Maginot-line with certain number of forces (until it is too late).
But then again, then you should also make Germany do maniacal things, like attacking the Red Army in winter turns, with very low odds/modifiers. Etc. etc.
But that's the exciting thing about WiF: we don't get orders from a maniac, or nestor generals who are stuck in obsolete doctrines that might have worked in another era.
Seeing your other post you are playing 2d10 or just started playing it. That option should make life much easier for the attacker,
so especially for Germany during the early years of the war.
An example. Compare a 2:1 Blitz-attack of two German panzer stacks against a french infantry stack with an AT-division and two disorganised corps, 1d10 vs. 2d10.
* 1d10, the attacker has 40% chance of all his units becoming disorganised, and a 10% chance of losing a unit himself.
* 2d10, the attacker has 3% chance of all his units becoming disorganised, a 7% chance of losing a unit, and 18% of becoming ½DG. If the French had an ARM/MECH division included, the chance Germany lose a unit would increase from 7% to 14%.
I call that quite an improvement for the Attacker (the Axis, because they are the aggressors early on and have first shot at victory). The total chance of any attacking unit becoming DG is reduced from 40% to 21% (18% being only ½DG). OK, the Allies will benefit from this as well once they are on the offensive, but that is later, after the Axis failed.
Personally I have mixed feelings about how land combat in WiF developed over the years; in WiF 4 (before the 2d10 option), when I started to play WiF, the chance that the attacker would be disorganised in the above example (Germany) was 70%, with a 40% chance of also loosing a unit. Not including Fractional odds, an option that was also introduced at a later point, IIRC. So over the years I've seen a rebalancing in favor of the Axis. I know, I should say 'the attacker', but I think Fall Gelb and Barbarossa and all of a sudden 'attacker' becomes 'Axis'.
Anyway, I am still somewhat happy with the probability distribution in land combat, but I have to hope WiF does not develop into an Axis and Allies sort of game, where both sides are given an equal chance to conquer the entire world and time works against the allies!
