Not saying these are at all perfect, but I posted about some potential Vichy house rules for 1940 a while back as well! Just thought I’d share here in case it sparks anything for you as well or anything to go along with your own!
I explain my thoughts in this post, but my hope was to avoid any massive deviations to the standard A&A game play. By that I mean, I didn’t want to go crazy adding or changing a ton of specific rules or anything that exist in the game already.
