That was the Kaisserreich Mod.
France becomes a Syndicalist nation.
The UK ends up having Soviet style Communists take over.
Italy is split in two. Syndicalist control the southern half, and Fascist take over the northern half with the Pope as their dictator.
Spain still ends up having a civil war, only this time it's a three way war between an Anarchist-Syndicalist coalition, the regular government, and a Carlist faction.
If the Anarchist-Syndicalist win, they ally with France. If the Carlist win, they ally with Northern Italy.
The United States has another Civil War. The factions are Syndicalist in the North, Isolationist who are still a democracy but dangerously close to going fascist in the South, the Pacific states breaking off, Hawaii declaring independence, New England seceding, and the American Midwest representing the loyalist, with the new capital being Denver and being run by a Fascist MacArthur.
The troubles in the US are supposed to be because the Kaiserreich has enough influence on the world economy to screw with America's economy and the Entente defaulting on their loans, which makes the Great Depression a LOT worse.
---------------
WW2 in the Kaiserreich mod is usually kicked off by Syndicalist France demanding the return of Alsace-Lorraine and Germany telling them to piss off.
Soviet Britain tends to side with the Syndicalist when they try to claim Belgium and Germany tells them to piss off.
Japan also tends to go after China.
