Why do you guys put factories on Asia? Seems like a waste to me. Japan only has enough income to buy 8 units for transporting anyway (can increase to tanks and inf later with more income).
If you spend 15 on IC, then you put 3 units there a turn, but you aren’t using Japan IC fully because money shortage. You gain no movement either (except through China corridor, which will be almost defenseless in a turn or two). You can drop from Japan to Buryatia which is just as close to Russia as any mainland IC. why waste 15 IPCs? I also build no ships until I see US pacific fleet amassed (which rarely happens). Since you took out Hawaii fleet (doesn’t matter what you lost as long as their’s is gone), they are not within reach for 2 turns. Only build boats in response to US massing.
I have made India IC though as income increases and you can’t spend all your money at Japan IC. This allows for pressure on Caucus at same time as northern pressure. Then I just mass at Yakut and India until I have enough to hit either Russia IC.
