Yes, I like building 3 transports as well as Japan R1. But I believe that the best way to kill the allies is a J1 attack on the 4 chinese territories, Shan State, French Indo-china, Kwangtung, Phillipines, and Celebes. I take all of these on round 1 and then take all of the DEI R@. This skyrockets Japanese income to 41 on turn 2 and like over 60 turn 3. I then steadily make my way through China and into India with a Malayan factory (useful for both an Indian and an ANZAC invasion). Thoughts?
A strong J1 does not need to involve attacking the US1. Waiting to attack the US on J2 or J3 keeps their economy hobbled while the Japanese player continues to see their economy steadily increase. By J3 they can be in a good spot looming down on India and building a solid defense against the US.
The problem with an all-out attack against all the Allies is that it quickly overextends the Japanese. Playing as India, I’m a happy many when the Japanese player gets hyper aggressive as Fire Knight suggests… I can fortify India enough to make it impossible to take Calcutta until J4+ - which gives the US a long time to build up. This also means that the aircraft the Japanese want to use to ensure victory in India will need to be diverted (at least in part) to the E. pacific to defend against the US. Worse, it gives the US the time and economy to reinforce Australia. 2 extra turns of 50+ IPC is a big deal - even if Japan is neck-and-neck simply because the US only needs to bring their might to bear in one (maybe 2) places while the Japanese, tied down in Asia, is going to need to have forces in 4 spots (India, S Pacific, E Pacific and usually one other place - often SW Pacific or C Pacific).
So far, I’m not sold that an all-out attack against all 3 Allies is the best idea.
