What a great mod!!! But there are still a lot of things to do ...
I'm curious about what ideas you'll be putting in motion for the next version(if you do have the time to work on this), but that being said, there are things that need to be thought over:
-first, you MUST help the danish IA to join the war on the side of Germany, because otherwise, it leads to an exotic allied naval invasion of Pomerania(Helsinki invasion everyone?)
- in the same idea, you must help the german IA to build garnison to protect: Poland (high dissent attracts like 15-20 div here), its coast(to make allied landing more difficult), and its puppet(RK norway destroyed by UK and almost destroyed RK Flanders everyone?)
-allow the annexation of mongolia as mongolia SSR (like "eastern turkestan"), because, playing as soviet russia, i doubt that there is any interest in keeping them alive
-allow the "communist" northern vietnam to join the communist camp ( to gain allies to figth the "capitalists pigs"

), and more generally, allow the rise of communist/ communist friendly government for the post war period(per example for the new countries in Africa)
-maybe more aggressive/reactive IA for the reich allies? (in one of my game as soviet russia, an english army has been trapped in Bulgaria (inland) and lasted until the end of the war, and Finland failed to drive back the english in Norway)
-and, after the end of "WWIII"(more like the prolongation of WWII), allies should return russian/soviet land back to its owner (border would be the same as 1939 i think, or maybe with independent Ukraine and Belarus)
And to conclude, why the fuc* does "Vichy France" be TOTALLY independent? I mean, in 1942, historically, Vichy France was only merely a name ( german troops having invaded the "free" part of France), and thus, having an independent and NEUTRAL France is a big problem, either make them a puppet of Germany (with high dissent thanks to the french "résistance" backed by the allies(at least free France), because i think an allied backed resistance movement would be the tiniest problem of post WWII Germany), or an independent nation allied with Germany (like Romania, Hungary, Italy)(plus, having the germanophile/nazi friendly Laval as head of state...).
Conclusion bis: allied of Germany having only 1939 like level of technology is obviously wrong, them having 1942 level would be logical (or 1945 depending on their strong point, per example Hungary would have 1945 medium tank ( 44m TAS))
And if you say that if i want these change, i should make them myself, i'm planning on working on how to mod this game after my exams ( in 2 weeks or so), and so, maybe i'll be able to lend you a hand
