Nice. I have no experience playing this game, so I do not know how much of this is due to the natural bonus of the Japanese in the early game and how much is due to your strategic thinking, but it sure looks good so far.
Could you attempt an attak on L.A./S.F. in the next few month, for fun and profit? Bending history so far would be awesome.
Its both. Japanese's advantage is that the Western Imperialist Aggressors UK and US have their interests in Europe(even US, despite only joining the war after Pearl Harbour), vastly superior training and experience of Japanese soldiers, certain technologies and innovations the Allies dont have(and some, like IR cameras and range finders for nighttime naval combat they had no equal until after the war). And then theres the surprise factor. Allied forces are spread out, optimized for colonial use, not war. Pearl Harbour and strikes on Clark Field and Manila that paralyze the US Pacific Fleet, kill submarines, wipe out almost all the modern fighters, and then there are the simultaneous, coordinated surprise invasions.
With the Allies rushing stuff to the Theater its starting to even out now, but unless I screw up something they wont have parity in both numbers and quality, in other than battleships and submarines, until early 1943. I will have to use the initiative and advance as (reasonably) far as possible while keeping all important assets, such as the carriers, alive. Every carrier, battleship and land division the Allies lost they get back up to 10 times. Every carrier the Japanese lost is replaced 1:1 - Japan only gets 8 Fleet Carriers during the war in addition to the 6 in the beginning. But only 3 of those 8 before late 1944. And every lost battleship is lost for good, as there are no new battleships other than Yamato and Musashi that will be built.
edit, yeah the other part. I have no idea why they have no air units in the area, or war ships... Looks like they're pulling a "Sir Robin" and pushing everything back ASAP and AFAP now!
