Hi Davide,
No there isn't any way not to show the results, but there is a way to change the campaign result text by importing a new text file with the description of the support assets for the selected ToO.
It will be stated that the player should select only one of the two flag locations. If he chooses both of them he will win a decisive victory and he will follow the second path/choise. The choice A is from decisive defeat to draw and the choice B from marginal victory to decisive victory.
So whatever a player do he will receive one of the 2 support assets.
In the secondary scenario, if the player wins a marginal or decisive victory he will follow the second path of the primary mission. If on the other hand he choose to simply walk by the map (taking the north road) he will probably score a draw or marginal defeat and he will follow the first primary path.
But if he chooses to not engage at all he will suffer a decisive defeat and he will lose the chapter (he will continue with the next chapter)
The basic scoring mechanism of the secondary mission is not based on the value of the flags but it is based on the value of some critical equipment (hostile mortars) that cost 800!!! points. So in order to win something more than a draw the player should destroy that mortar units. In the enemy camp there are also some high value VP flags.
If the player choose to not engage and take the direction of the north path he will still engage the enemy (few low quality troops) and he will conquer some VP low value locations (because these locations are low value the AI might ignore them in the reaction phase and probably won't contest them). The game will probably end with a draw in the "not engaging" condition. If the support elements manage to kill many hostile units (scoring this way a marginal vic) then I will increase the value of the flags inside the arty camp.
The whole point is to play with the "draw" - "marginal" victory conditions or with the "decisive" - "all the others" vicory conditions.
Anyway these are the first tests of the theory... so be patient!
ciao,
Pyros
