Works ok given the limited countermix. The Japanese are painfully strapped for supply, whereas the Allies have no real problems. Here there are some restrictions, because ports are rated for supply capacity strictly by their historical degree of use, so an Allied player who falls back to Sydney from Noumea has a problem. Carriers are individual, battleships are two per counter, other ships are grouped. The map is mounted, in four Squad Leader-style segments.
Amphibious landings are of course there, with land units standing for their own transports.
Both sides' capacity in that area is fairly restricted depending on historical abilities per game date. Rules are about 24 pages, so I'd rate it upper half of medium complexity.
