Alright, uncivil_servant, I'll bite.
1: So many units are restricted (Dutch islands)(Philippines) meaning one has to move heaven and earth to do a more organized DEI or Philippines defense.
Quite historical. Otherwise, we'd no doubt see Phillipine units defending Palambang or something akin to that.
2: The ability to have enemy fleets be anywhere in huge area without same ability for allies to react to that.
That's not really true. The Allies can't contest the Japanese carriers for the first four months of the war alone, at least, but there's plenty of scope for operations wherever the IJN isn't. The real problem is getting the Allied naval assets concentrated.
. Sonar guided torpedoes for the IJ forces makes most actions with moving troops or reorganizing or putting up a fight inherently stupid. You will be sunk. Almost guaranteed.
Wrong. Operating ships without air cover in IJN torpedo bomber range is a sure way to be sunk. It's the lack of suitable long-range escorts that hampers the Allied navies in the early war, which is quite historical.
4. The complete ineffectiveness of non-torpedo land based bombers. B-17s out of Clark scored hits on their attacks on enemy ships every time they tried (transports then Ashigari - but they only had a minimal bomb load so light damage), then at Midway they came so close to a carrier that it was was described from adjacent carrier commander as being completely obscured by the plumes of water. They couldn't sail just outside of Sydney and laugh at the attempts to attack their ships because they program makes level bombing scoring a hit a very rare thing - hence no one is afraid of allied air forces.
You've a point, but this falls to personal taste. Simply amassing a flotilla of 200 B-17's and sending it after the IJN might be a "cheap" route to victory in the eyes of some. 200 B-17s with 8 bombs (1600 bombs total) each gives you an excellent chance of seeing some hits on IJN ships regardless of the altitude, and it's a move that the Japanese have no real counter for.
5. I cannot use smart tactics to save the troops in places like Bataan, whereas if they had brought supplies wit them they could have lasted much, much longer, the game makes the defeat inevitable on much the same time rate as bombing airfields uses up their food to repair them as the player is not allowed to "ignore" repairing an airfield with no planes.
What smart tactics? The player can stockpile supplies in Bataan, as well as bring supplies in via submarine. The bombing of airstrips abstracts bombers attacking supply depots, and I very much doubt that every Allied supply depot in Bataan was untouchable by bombing.
6. I have to hide my air forces as high level sweeps will force me fight them instead of wisely declining to fight and letting AA guns start firing into the fighter formations, making them choose to either come down to levels where I would be willing to engage them, or exit the air space but AA, in the game, doesn't defend against sweep attacks.
I agree. AA should be part of the combat routine, but only on unopposed sweeps (lest the combination of flak + CAP makes defending far more advantagous than attacking) and only have a real effect on fighters at low altitude (seeing as fighters don't need to rigidly line up for bombing runs).
7. I have to really trust the other player to 1) play through to when it isn't all IJ victory after victory and b) if what I read was true - that for some ungodly reason the IJ player can keep playing/reloading the turn they receive until they get results they are not diametrically opposed to.
(Speed limit effect with no cops - people will speed - guaranteed) Sense of fair will might win out sometimes but if it is possible to do that, I guarantee as human nature it has been done)
It takes a rare type of person that's willing to play Japan, where they know they're going to lose from the start, and need to delay that defeat for as long as possible and where mistakes that lead to the loss of Japanese troops, ships or planes only increase the massive disparity in resources between the two sides.
As for what you say about reloading turns, it's impossible. The Japanese player has no access to the turns results until the Allied orders are inputted, so how would he know said results?
