@Cow:
In the Pacific I go into every game with the high hopes of winning in the Pacific. It happens sometimes. Crush india J3 or J4 and hope things are going well enough to take Hawaii someday. Sometimes it happens, sometimes I bust, sometimes I am forced to just have Japan, India, SEA, and all my ships air died, but hey I gave it a go!
I find the J1 works great, especially paired with something like your G1/G2 strategy.
Hong Kong, Borneo, Phillipines, and Yunnan on J1 with a factory and 2 transports
J2 is the money islands and my fleet protects 2 of the transports for sure, as best as I can (Sumatra is within UKPac air attack range easily so is usually not worth defending) and new transports can shuck new ground troops south. Subs head towards India. Bomb India on J2. Often do the factory on French Indo-China.
J3, usually take Malaya and might gather fleet there (or over Philippines if U.S. is seems aggressive) Subs move to convoy India. Bomb again if I have to. I don’t bother pushing to take India. I’m more interested in locking down my income (money islands) while turtling India and looking for a chance to destroy China or India’s stack of infantry. Japanese fast movers push towards Moscow’s back door, too. J3 I’m usually collecting close to 60 ipcs and rarely go back down again.
If I can hold that for 2 or 3 turns, that’s usually it for the Pacific side. From then on I’m just whittling away, heading west and looking for an opening to sink the U.S. and/or ANZAC fleets (by positioning at Japan and Philippines, everything I have can hit them at the Carolines, for instance). By UK3 UKPac is only making 10-12 ipcs, their factory is bombed, and 2 Japanese subs park off their coast so they often can’t buy anything for several rounds. If they leave Calcutta, there should be enough Japanese land and air to annihilate any stack that adventures out. China might have a stack of inf left, but are whittling down, and ANZAC can’t earn enough to do much until their turn 4 or 5 unless they join the U.S.
My buys are pretty much only mechs on the mainland, maybe some tanks, a 3rd or 4th bomber maybe, but otherwise just carriers. Japan has so many planes that buying carriers is a very efficient way to have a strong defense. Each 16 ipc Japan spends on 1 carrier means another the U.S. has to spend to destroy 4 hits defending at 2, 3, and 4.
If I can turtle UKPac, don’t lose fighters/tacticals, and buy enough carriers to keep the U.S. from taking sz6/Korea, I only need a modest fleet on the Philippines to keep the money islands and counter attack the U.S. if they do hit sz 6. I try to keep 2 transports at Philippines so ANZAC can’t poach an island. If I do that, by J5 or so I’m about on par with the U.S. for income and my defense fleet is a beast. I’ll do a huge sub/destroyer purchase if I think I’ll get to attack him instead.
Fast movers driving through China give me a backdoor option to help hit Moscow with Japanese planes after G6 - I’ll even buy more Japanese bombers to help if Germany isn’t max bombing Moscow already. If I have a spare transport or just plenty of mainland troops I might start hitting Russia’s far east, too, Mongolia rule be damned, as long as troops in China can keep the Mongolians from reaching Moscow in time to help that defense.
