Uncle Joe-
In both of your and our games, the situation appears to be about the same. I agree with your numbers in the broad sense (though I think Japan is slightly lower-65 rather than 70). Its what happens next that matters.
At roughly the end of turn 5, your numbers are approximately right. Japan has taken India, China, Australia, all of the Pacific (more or less-maybe not quite all of China, maybe all of China but not yet Australia, but generally right). US/UK have landed in Morocco (or have landed, and perhaps been kicked out of, western Europe). Germany is on the defensive in the East (probably holding Poland, perhaps holding one or two of the border regions in Russia). Russia is getting the strength to continue pushing west. italy/Germany hold the top part of Africa (minus Morocco) and perhaps part of the interior of Africa (from blitzing German tank).
But now, US/UK threaten to either permanently hold western europe or conquer Italy (and take their money), and will be pouring 6-10 ground forces into Europe per turn. Thus, Germany/Italy have to defend western Europe. Which allows Russia to continue to press from the East (into Poland, into Rumania/Balkans, wherever Germany is weakest). Germany/Italy lose their national objectives (US/UK in western Europe as well as Morocco-sometimes Gibraltar just to ruin the NO). ON TURN 6: Italy probably falls. Poland possibly falls (and Germany proper is now threatened by all 3 allies).
Japan: to achieve 65 income, at the end of turn 5, they have: a fleet down in Australia. A fleet in India. Some (not alot) ground forces in Western/central China. some (not alot) ground forces in India. Factories in Japan and a few coastal areas-perhaps Manchuria, Vietnam, maybe even the islands in the Pacific worth 4. Thus, ON TURN 6: Japan build a whole bunch of ground forces-in Japan, in Manchuria, in Vietnam (which are 3 turns from the front lines!!-they won’t be in the fight until turn 9!). The fleet near India can threaten Madagascar or the east coast of Africa (worth maybe 2-3 income). The fleet in Australia spends turns 6,7 and maybe 8 just getting somewhere useful. The ground forces in China and India plod one space forward-to the space west of India, to the space west of western China-for another 2 dollars.
In short, I think your and our games are pretty similar at the end of turn 5. But turn 6, Italy falls, Japan builds a bunch of stuff in Japan, and captures 4 dollars worth of irrelevance in central asia and east africa. Japan may be a monster, but its an irrelevant monster.
It sounds like the German/Italy players werent playing with an eye on survival (ie, they were actually trying to make headway into Russia) and the Japanese player has been building for the immediate advantage rather than the long-term advantage.
The only time I’ve seen a KGF succeed was when we had a lesser experienced Japanese player and they failed to coordinate with Germany/Italy. Sure, they had an income out the wazoo (the 65+), but as you say, they werent ‘relevant’ to the rest of the game. The trick is to MAKE Japan relevant. And as I’ve said before, the easiest way to do that is ICs in Asia churning out tanks (about 6-8/turn) and especially bombers to support the tanks and remove Russia’s econ. At the very worst, I’d be prepared to trade Italy for Russia, but I dont think that even has to happen if Italy has been playing with an eye towards simple survival.
IMO, once the Allies commit to KGF, THEY are ‘on the clock’. With a monster Japan, its only a matter of time to Russia is GONE (much faster if Russia cant build units due to Japanese SBR). So with that in mind, Italy and Germany’s SOLE goal is to survive. Trading your whole air force for the Brit fleet is worth it if it costs them 2 turns to rebuild (at LEAST, since her econ is going to suck). Beyond that, infantry and planes while the econ holds, then infantry/tanks and finally just infantry. With even EQUAL econ, I really dont see the US and UK getting ahead at that point. They just have too much overhead and too much to protect from air power to be able to land into 10-12 infantry and a few planes.
Finally, since its all about TIME for the Axis, the Japanese can cost the US time by invading Alaska (which forces a defensive commitment and/or a counter-attack) and threatening Mexico/Panama etc from the Pacific. As was noted, there is nothing that says that Japan’s fleet has to stay in the Pacific either. Since they are likely to be taking Africa, its not much of a stretch to get some CV’s into the Med or South Atlantic. Which again, greatly adds to the US/UK headaches of protecting their fleet. Germany can hit any fleet with air, followed up by Japanese air (including bombers which can easily stage to Poland).
Personally, I think the Allies have a very good chance of winning the game, but not with KGF. A good Axis TEAM should be hold out until the Cavalry arrives.
