Wohoooo! Game won!
I'm only really interested in WWII, and by '44 Nationalist China had conquered Manchukuo and single-handedly conquered Berlin while the rest of the Allies played around with France and the rest of Germany.
The US had taken care of Japan, and Japan's troops in the continent were slowly but surely destroyed. I found out about encirclement, which is awesome - but a bit too easily exploitable. Basically all I had to do was let a largish piece of land open next to the shore, and let the AI rush in and adjust bring troops to the new borders. Then I'd push one or two provinces against the coast, cut a dozen divisions off, and completely destroy them.
I don' think things improved that much from building infrastructure. What I ended up doing was having units at low org strategically redeploy to a city not horrible far from the frontlines. That'd get them supplies and get their organisation up really fast. Then I'd bring them back.
Organising the army and commanding corps is still a big pain. I'm trying to keep 1 Corps per province, with 4 divisions each. I have to select one of the divisions, find its HQ, click on "divisions" to select the HQ+all divisions, then remove HQ, then move them. It's a big pain. Please tell me there's an easier way?
Also, is there any way Japan can survive the late war? I doubt it, right?
Thanks for the help, everybody. Nationalist China, Conquerer of Berlin, approves!
