I would also like to point out a few things from the MP games that me and my friend has been playing.
Cold War 1945
Kruschev doesn't rise to power in the Soviet Union after Stalin's death. It is now 1957. Molotov holds both the HoG and HoS posts.
Finland remains completely apathetic towards USSR, very unlike RL post WW2 Finland.
Iran remains a Brittish puppet.
Wouldn't mind some edits to make sure the AI builds nuclear reactors if they have the technology and decent IC, the British AI seems to do this on it's own though, which is quite cool.
Could use some events to cause various nations, especially in Latin America, drop out of the US alliance.
China seems to keep dowing both North Vietnam and North Korea anytime it gets the chance, and relations remain at -200 as soon as the Korean War erupts. It is also ridiculously easy for the USA to win both wars on it's own, at least if played by a human, not to mention in the Korean war South Korea for some reason did not join the war, but the USA and allies fought (or more like steamrolled) by themselves against North.
Almost all nations, especially the great powers and USSR suffer from enormous lack of resources due to the low ic efficiency. USSR becomes the world's largest importer of oil, rare materials and so on...
Both Germanys build massive armies in short time (in RL army size was limited, no army was permitted for FRG until 1955).
Japan becomes a military superpower in almost no time, with numerous aircraft carriers, battleships, a hundred divisions or more and so on. (Japan also had strict limitations after the war)
Chinese civil war ends too quickly, so the Berlin Blockade never ever happens.
Think you could fix some of this? Of course we are fully capable of editing the most serious issues from this on our own, in our own game. But solving them in full certainly would improve your most excellent mod.
