This variant makes the US too powerful - I agree with MistaBiggs. USA gets a factory on China, Japan doesn’t have enough to capture the territory. :cry:
Although, this would enable Japan to attack eastern Soviet territories without being attacked by Russia first. Also, this gives Germany a shot at attacking Leningrad with ALL of its airplanes and tanks/infantry within range, and with great luck of the dice, possibly capturing it before Russia has a chance to strike Scandinavia with its planes and tanks. :D
