Here's my count of what's out there and I know there's more coming:
In the beginning was USN. And it's been done in a Second Edition by Decision Games, USN DELUXE.
Next up was WAR IN THE PACIFIC. It too is in a Second Edition by Decision Games.
PTO is another by Decision Games and is now ADVANCED PACIFIC THEATER OF OPERATIONS (just been released). So right away we have three of these babies all currently in print by Doc Cummins/Decision Games. How about that.
Victory Games did Mark Herman's PACIFIC WAR. So successful in its design, the redesign of WAR IN THE PACIFIC lifted a good deal off it.
AH had the old EMPIRE OF THE SUN which has been redone and absorbed into Bruce Harper's/GMT's A WORLD AT WAR (now being redone yet again, I'm told).
Avalanche Press has the "streamlined" GREAT PACIFIC WAR which shares much of the same system with John Prados's THIRD REICH (not to be confused with the older editions that AH had--this is a good bit different).
Pacific Rim has gone a big game in the works, but it has yet to see the light of day. GDW used to have PEARL HARBOR, but nobody has clamored for that game to come back.
Games that may or may not be considered monstergames, depending on your definition include Task Force Games EAST WIND RAIN, Hobby Japan's PACIFIC FLEET, and GMT's EMPIRE OF THE SUN
Regarding subtheaters/campaigns, there's MMP's OCS BURMA game, GRD's WAR OF THE RESISTANCE and THE DAMNED DIE HARD (both in the Glory! Europa derivative). I am not going to count Avalanche's TIGER OF MALAYA into the monstergame category, although some will beg to differ. But I will include the massive LEYTE GULF game, part of the Second World War At Sea series! And if we're going to do that, I suppose Battleline/AH's old FLAT TOP, Yaquinto's CV, and other naval games ought to be included. But I'm loathe to do that in this particular discussion group...
Which ones do you like? Which ones turn you off? What are your favorite Pacific War monstergame stories?
