I don't doubt that the Japanese could have played things differently and perhaps done better. But the allies could have done so too. The initial defence of the Philippines was very poor although they then held out well later on. Malaya should not have been lost at all. At least until the Japanese brought in more land units and ringed Singapore with air bases to cut it off. Yet in WitP these two bastions fall and fall fast. They are not much of an obstacle.
The inital defense of the Phillipines was very poor because of MacArthur's faulty planning before the war. If I recall
correctly his predecessor had planned for a fighting retreat to Bataan which would have been fortified and well stocked
with supplies. MacArthur believed he would be able to stop the japanese invasion at the beaches, which didn't work so
well mostly because the japanese failed to show up on the particular beaches where they were supposed to land.
As to Malaya I also think the main errors had been done before the war (like not sufficiently fortifying Singapore even
though it was supposed to be the cornerstone of the Anglo-American defense of SE-Asia and also not stationing enough
troops and planes in Malaya). I don't think that given the circumstances (japanese control over the sea and air) Malaya
and S'pore could have been defended for much longer than historically happened.
If I remember Toland correctly the British had even pleaded for American forces to be stationed in Singapore in the thirties
which Washington denied (Apparently neither the British nor the American were certain that Malaya could be held even
though they claimed publicly that Singapore could never be conquered)
The most important reasons for these japanese successes were there before the time covered by the game.
As for China I suspect the IJA could have taken more territory. But they would have had to commit a lot more troops and air units costing them in other areas. Not in WitP where they appear to be able to have the numbers on hand already.
As has been said before the japanese did not really try to win in China. It had no strategic perspective for them because
they never could have held control over the country after the war and they did not want to either. The whole war in
China had been a no-win situation from the start and most japanese realized that. If there had been a face-saving
way to get out of the war all but the most idiotic japanese Army General Staff officers would have been glad to leave
China to the Chinese even before the start of the pacific war.
If the Japanese could have succeeded in taking China if they had been willing to pay the price in casualties, who can
tell?
Likewise in the Pacific. With KB and some extra LCUs and air groups they probably could have gone for Noumea and Fiji. But only at the cost of slowing their advance some where else. Either Burma would have to be delayed or put off. Or the mopping up in the DEI being delayed. Not in WitP though.
The problem with this is two fold. One is historic. The other is from a game point of view.
The historic one is that the Japanese - even with moderate play - can far exceed their historic advances without really trying. The historic counter moves by the US are simply foolish in this game. This means the Pacific Campaign is likely to be conceded totally by one side until with the new Essex's and Hellcats allow him to reverse this.
The game one revolves around game choices. Apart from extreme strategies like taking Russia (although it's apparently one sided and easy) the choices are all idiot ones.
Do you take China or not? If it costs practically nothing and your going to kill vastly more than you lose it's a no brainer. There is little or no division of men and material from other theatres. Who wouldn't?
Taking Singapore easily and early? Who wouldn't. You don't even need to use your valuable Betties and Nells to cut it off. Sallys and Lillys routinely hit transports and destroyers. They largely ignore the pitiful Buffalo CAP (should any remain after a few Zero and Oscar fighter sweeps and bombing raids on the airfields). Then of course you are ahead in the game and able to go for Java/Palembang or Burma even sooner than in history.
Take Noumea and/or Fiji practically unopposed? Who wouldn't? You disrupt the supply lines to Australia and the allies cannot interfere or they risk losing their CVs to KB. They cannot be made secure. There are just not enough allied planes (nor any Betty type LR anti shipping planes) nor are the few available skilled enough to be worth risking. Again it's just a win - win strategy for the Japanese. Fairly easy to do and gains a lot. With a potential even bigger plus of attracting out the allied naval forces to their doom. If you think this long term over extends the Japanese you can always abandon them in early '43 before the Hellcats arrive.
These are not hard strategic choices with trade offs. Nor really do they require great skill. Most WitP players advocate not even trying to stop the Japanese getting them [X(] So Japan can do them all and more. If you have counters to these please let me know. Or areas that the allies can hold out for longer than they did historically.
Fortunately the editor can be used to address many of these things.
Again I think if Midway hadn't happened the Japanese could have gone much further if they had wanted (which they didn't
because they had overextended themselves already and many Japanese Admirals knew it)
With the full KB around the Solomons Campaign would have looked much different and I doubt if the US Navy would have
forced the issue at that point in time. Instead, the Navy would have avoided offensive operations apart from quick raids
and waited for their shipbuild programs to bear fruit (which appears to be the prudent strategy in WitP).
