-Assigning 1ipc values to the Pacific Islands would certainly help and encourage Japan to invade them but I doubt USA will try to retake them. For balance purpose, Japan has to start with significantly bigger fleet than the Allies. It requires minimum 15 ipc (transport+destroyer) just to invade one of the island with a protection. Even if Japan lose some of them, she is still capable of compensating these loses with another conquests. While if USA just ignores Japan, the huge Japanese fleet lose its all combat value suddenly for a long time.
-Yes, the capital rule does not make sense. Nations should be able to collect income and mobilize units even if their capitals are fallen. Also no losing all of incomes when capital is lost.
-That’s why I think Germany is too weak and Japan is absurdly too strong in A&A games which should have been the other way around and it results Germany just spamming infantry and waiting Japan ro rescue. It makes no sense. Historically by far the strongest Axis country should not have badly needed Japan’s and Italy’s helps to just stay even alive. This aspects also encourage USA to go only one front since if Uk-Russia is strong enough to defeat Germany-Italy. USA could choose to go Pacific only to just secure the British colonies but still no two ocean going USA unfortunately.
-Ipc vaules are known very abstract but still it would look very weird if these Pacific islands worth more than 1 except Hawaii. For example Australia was obviously a lot more than twice valuable than Guinea yet having Australia just twice valuable than Guinea is somewhat justifiable for playability but Australia cannot be same with Guinea. It would totally negate all WWII feelings as much as the Japanese tanks storming Moscow.
If Guinea becomes 2 then Australia should be minimum 4, India 5 or 6, South Africa 3, Egypt 3, Hawaii 2 etc.
-Having both Indian and Australian factories can actually help Japan more then Allies since if Japan concantrated southwest Pacific with East Indies Factories, UK might find itself spending more money than Japan in this area to just defend these factories because the Japanese units will be in range in both factories simultaneously considering USA needs 2 rounds to reinforce Australia.That’s why I’am fine with Indian factory but not with Australian factory.
-A solid way preventing USA going Pacific only is making UK-Russia doomed to fall without strong US assist in Europe. Preventing USA going only Atlantic is uhm… well I do believe not possible in A&A maps with its rules and cost structures. Totally needs redrawings, revaluings, new rules and costings.
-Expensive ships discourage naval investments for both sides when fighters just do well better than them with similar costs. Destroyer is too expensive for even mimic infantry abilities on sea such as blocking, baiting, deadzoning etc. Of course reducing ship costs do not magically create two ocean going USA, it is just one of the indispensible condition to achieve that. The expensive ships also reason too why Germany and Russia don’t build navy either.
