We got up to Summer 1942 and stopped. We’ll start again from the beginning since we have a better idea of how to play Japan and China in that crucial first year. So far, it feels as though China will hold out until Japan has to pull away to occupy the islands and attack the British and Australians.
The carrier planes should be put to more use against China, but then they will need to be redeployed to the South Pacific along with most of the fleet. Despite teh huge monetary advantage the US has ($100/turn) because of the long build times for capital ships, it will be 1943 before the US really gets going.
Of course, we need to play that far to see if it happens that way, but it seems like it should.
