And it is possible to get to the Commune before the Germans, at least as a Canadian player. You just need to form an alliance with the Papacy (difficult but doable), station a bunch of troops there, and intervene where ever possible (I was able to take the Northwestern corner of Spain from the FAI and Michigan from the CSA). Germany seemed to be making headway a bit, but France took Wallonia and a stalemate seemed to form, so I figured the stalemate would be tying up the Communards in Belgium, and took the opportunity to invade via Savoy and Rochelle. By the end most of France was under my/Rome's control, and I barely was able to take Paris before the Germans, and with most of France under my control I figured the Germans would consent to give a small sliver of French territory in return for Wallonian land so I reloaded as Nat France and demanded the territory.
Also, as the descendant of leftist Pied Noirs, I find it sad that Camus isn't a possible minister for a democratic Nat France.
