Im sorry but this makes no sense to me. How is Japan getting to 70IPCs BEFORE America enters into the game? I mean it is possible, but not with out taking down the Uk in India and the Chinese and grabbing chunks of Russia AND taking the DEI. This is stretching Japans resources in several very different directions, meaning their overall strenght would be weakened by being spread out. This is no way you can achieve a 70IPC by spreading Japan out. You will need to focus japan at ONE objective first (like the DEI) and take that out right before you could move on to another (like taking Calcutta). Now I could see you being able to take the DEI and then be in a good position to push for Calcutta, you’d be in a prime position, and the DEI will double Japans economy but that still only makes it about 45-50IPC, while the US will be at 80IPC. Meanwhile you’ll still have to hack your way into India which means you WILL need to buy reinforcments for this front. So your fleet is being concentrated in the south and west of the pacific, this gives the US free regin, along with the ANZAC, to do what ever they want in the south east and central pacific(land on lightly defended islands, convoy raid, pick off lone ships) with Japan unable to do much to stop them, for atleast several turns unil they resolve whatever they are doing in the South and against India. Whatever you after you size the DEI, America would be able to match WITHOUT needing to spend the 90% income Grasshopper is suggesting.
