@SSG:

Unless there is more information than a major battle in the Pacific, it could be any number of the islands or sea battles (Iwo Jima, Guadacanal, Saipan, Tinian, Battle of the Coral Sea, The Marianas Turkey Shoot, Okinawa, and many others)  How about a fictionalized invasion of the Japanese home islands?  The battle plans for the invasion and Japan’s defense are available, now from archives.  Secret weapons available for the Japanese could even the balance of power (without the A-bomb).

There are several interesting possibilities.  It should be an interesting game. :-D

I would like to see an Axis and Allies Iwo Jima game next
