With the exception of a dozen or so carriers operating in the north Atlantic helping the Brits keep naval superiority (and have it they do: 72 KGV BB's sail the high seas, compared to two lonely and soon sunk Bismark class ships), all operations have been on the Pacific front to date. Oh, and Mexico pissed me off so I conquered them.
Japan has had major problems from week one of the scenario, probably from all the American pressure. After fortifying Guam and Manilla with ships, fighters, and bombers, taking Truk, and then finally moving on Okinawa in early 1940, Japan countered with a seemingly endless stream of Yamato BB's, delaying the invasion of the Japanese home islands until late 1941. Finally a sufficient force of 100 or so Dauntless bombers was built up based on 20 CV's in the western Pacific and the Yamatos were sunk as fast as they were built. Then the marines and artillery began arriving after the long voyage from California, and Japan fell in a few short months of heavy bombing. Through this, they were unable to take more than a few Chinese cities.
The bigger map seems to have benefited the UK more than anyone. However they have done it, they are at least 5 techs ahead of me, the second place nation. Germany is almost hopelessly behind, and if it weren't for the initial tech gap for ground troops, the Brit Comet tanks would probably have established a beachhead in France by now. Brits with the best tanks in the world at the moment... go figure. Then there's what they did to Italy... most of their cities are razed, including Rome. North Italy remains, only because German tanks were able to kick the Brits back out, taking Naples as a protectorate in the process.
State of the war summary: Japan and Italy are no longer world powers. Germany and Russia are at an uneasy peace after a short and bloody German advance, stopping short of Leningrad, Moscow, and Stalingrad. After cleaning up Japanese Korea and China, 100 upgraded USMC units will be departing with heavy carrier escort to smash a stagnating Germany and put an end to the war, probably within the year. Who knows, perhaps we'll march on to Moscow, just for the fun of it.
Scenario reactions: Most of the US air units are useless. Of all 15 or so available in the scenario, only 4 or 5 are of any value whatsoever, the rest being later, inferior units. The UK is possibly too powerful to start, with more cities in Britain itself at high production rates. German naval production never stood a chance, and the AI never builds enough planes to jump start an invasion with an inferior navy. Also consider blocking the Northwest Passage north of Canada again, either with land or ice. Germany probably would have fallen already if the British navy hadn't sailed with 10 or so full transports around to the Pacific to "help" with the massacre of Japan.
AI rant of the day: it just has no concept of naval superiority, let alone air superiority. I mean, 3 Yamato BB's escorting a transport with a single marine, being diverted by a little blockade of DD's while being massacred by Dauntless bombers in Guam... how silly. The US Pacific fleet wouldn't have stood a chance if Japan had used the 25 Yamatos they'd built up at one point agressively. Oh well, nothing to be done about that except buy Civ IV and hope it's better.
That's all for now, thanks for the continued support!
