Hey Folks,
I think the main problem with any kind of “Magino-Line-Rule” might be, that it completely alters the balance of the game in favour of the Allies. If Germany can only use her ground forces in Holland and the 4 Mot.Inf from Western Germany allong with her Luftwaffe to capture Paris on turn one, there is either the risk that France survives the first attack on Paris (and gets to buy 6 more infantry) or a greater part of the Royal Navy will survive G1.
(Okay, maybe this won’t be a problem since it will balance the game more than any additional income or set-up for the Allies. :-D)
Greetings,
Lars
