Altough I didn't check newest version yet, I'd like to give you some suggestions about storyline. During gameplay I expected some things that should be improved.
Playing as Hungary, I centralised entire monarchy under Hungarian crown with exception of Bohemia that became my puppet. Later I anexed Poland and White Ruthenia(they left German alliance along with syndicalist Ukraine when some national-populists got in power in Minsk). Then I allied with Germany and in a year WW3 between Mitteleuropa and Syndicalists started. CoF was realy strong and it would destroy Germany if I wouldn't send all Czech and Lithuanian troops to their help. With my armies I destroyed Sicilian republic(they have united entire Italy before) and stucked in western Italy where French massed their troops. It's all nice this way if I wouldn't experienced strange thing in east. Three orthodox allies gobbled Bulgaria and during worst fight with France they attacked me. Luckily, Otomans were German allies and I could stop their advance while Germans accepted peace with them so things went back to status Quo. Even stranger was thing with Ukraine, that went Syndicalist but it never entered Internationale. It is strange to have problems with some Balkan alliance while Ukraine stays isolated with their 50 divisions even if they could attack my back and claim Galizia. I think that Ukraine should have great chance of joining Syndicalists if Khruschev gets in power. I loaded as Ukraine but didn't even had a chance to enter Internationale! Otherwise, breakup of Ukraine and Belarus with Germany just makes two useless and isolated nations on east that play no role in storyline. Even Russia went Social-democrat and they stayed isolated so eastern ''front'' was very quiet. Even leftist Georgia stayes quiet altough it has chance to stab Turkey in back or at least attack Azerbaidian.
Other ''quiet part'' is America. Both north and south. In south America Brasil and half other nations goes syndicalist, but they don't make any further steps. Even rightist Argentina goes democratic and stays out. North America is interesting with it's civil war, but there's a vacum after war. I think winner of war should ally with ideological friendly bloc(CSA with syndies, AUS with Germans, USA with Canada, PSA stays neutral or fights Mexico). Canada would be realy happy to have some American help in war against Syndicalists. In my game USA won, but stayed isolated dictatorship.
Otherwise, I realy enjoy your mod and I wish you good luck with further developmnent.
P.S.:
I saw that you included new music, it's nice to hear some Prussian and Austrian marches. I hope you will include even more music for all fractions, maybe you should use some eastern music for Asia too. I have a question about American Union State. Is this nation meant to be heir of Confederation? I heard Yellow Rose of Texas in game soundtrack, it is probably used for them? If so, maybe you should add more Southern songs like To arms in Dixie maybe?
Cheers
