But territory, for ANY amount of time, is income. And income means units.
For example, game I am currently playing, Russia pushed out into Manch, Karelia, Belorussia, and Ukraine. Germany pushed back, so did Japan.
BUT…
Russia is about to build $34 worth of units in R3.
Germany and Japan both lost about the same number of units in their counter attacks as Russia lost
Even after the counter-attacks, and before Russia moves again, Russia STILL has an income of $25, and will probably be at $28 after R3.
Not to mention that US still ahs Sinkiang, and India is going to be liberated by Russia for UK.
That means the Allies are significantly net positive on units.
I did not hold all of that territory, that is true. But last turn the Axis was fighting to regain their own territory, instead of invading mine.
