Do you really need America? I can just make a good Hawaii. Do you need Britain? They had no major role in the Pacific theater. Do you need India? The pacific is very vast and I think I could make better terrain with all the correct islands (Hawaii, wake, guam, iwo jima, japan, east coast of china, phillipines, top of australia), rather then trying to stretch it out too much. The main tactic used by both factions in the pacific theater was called "Island Hopping". They battle the enemy, 1 island at a time. India and east America is irrelavant. Rather make a good japan and hawaii for both sides main bases.
