Yes, in recent games the Germans are taking more Russian territory and thus increasing their income and denying the Russians their income.
I guess that when you fail to take Moscow you go for a long game (14-15 rounds).
Do you attack USSR with Japan? I usually do. The plus side is the russian are getting less, but all too often, it sucks valuable Japanese ground forces needed in China in the early game.
I agree with the above post - I’m not sure what the UK is doing if the Italians are running hog wild in the med. It’s never been that hard for me to just neuter them with UK if I put a little effort in.
Also - as has been said - Japan should have Calcutta out of the game by the end of J4. If you’re short a TT, build an air base in Siam or Shan and take ceylon J3 so you can leverage all your material.
Germany should be able to topple moscow or take everything else and just have so much income that it falls eventually as long as you STB the factory.
