@Black Ader Thanks for the great feedback - here are my responses.
Few remarks/bug finding for this most excellent mod otherwise :
-Hitler is supposed to survive Elsner's bomb all the time on normal difficulty, but he was killed twice, albeit I was on normal.
Definitely a bug that I'm not aware of - is this one of the bombing assassination events? I've noted it down to check this out. It should never happen on normal.
-When I closed to Moscow, I had a message saying that Staline withdrawed from Moscow. The capital moved to Gorky. However, when I took Moscow, Staline HQ unit was there, and another message said that Staline is dead.
This is a bug that I've had trouble figuring out, so I've removed one of the "Stalin's death" events for the time being in my current work.
-After Stailne's death, HoS was Kalinin (plausible), and HoG was...Kerenski ! I'm pretty sure that he was exiled in USA at this time, and I can't imagine Kalinin, Beria and Malenkov recalling him to save USSR.
I've made it so that Beria is always appointed HoS once Stalin dies. There was a good discussion on this several pages back that lines up with your ideas.
-Japan never launched attack on Pearl Harbor. I suppose that it is because they performed so bad in China (losing half of Manchuria) ? Something should really be done for Japan...
I've made large improvements in the Sino-Japanese theatre to help them out a bit. It now results in a stalemate, as it did historically, almost every time.
-Another miserable failure is Italy in northern Africa. But it is an old problem, and less annoying than Japan.
I haven't touched this theatre yet but may do so in the future. Italy almost always fails in Africa.
A final thought on Barbarossa : first month is decisive. If I fail on primary encirclement, I will soon be pushed back to Poland. But on the other hand, if my early stage is victorious, I will be safe more or less untill the end. I didn't took Moscow to taste the russian winter, but it was frankly quite calm, and 1942 wasn't really a challenge.
This has been my experience as well, though I've made some serious balance changes to the USSR that I have yet to test out. They will build a lot more ARM much less aircraft now.
Just an added question about Italy, I notice that when you take the decision that reorganises the military, it sets the strength of all the units to 70%, that never seems to change, even with mobilisation, is it permanent?
