I like the idea of Germany taking S. France to assist Italy.
My advice is: Keep in mind what the REAL job of the Germans is: Kicking Russian butts.
Many players lose their axis games because they neglect that nr1 central goal Axis have in G40 and do to assist Italy or do other stuff instead:)
And that exact reasoning almost cost me the game. Were it not for a sneaky Germany/Italy move the Axis would’ve lost that game easily.
It seems the best you can do with Italy is just try to build up a large ground force to stall any landing invasion from UK or US.
