Today I played my fourth game. I was Japan and the allies were played by one person.
I wanted to check if waiting to DoW is worth the while. I waited for two turns and concentrated everything on China and a build-up on the Carolines. China was getting smashed quite a bit, because I used about half my airforce with my ground attacks.
After my second turn the Brits attacked me! It cost me two transports and a couple of smaller ships. Also they reinforced the Chinese with some inf. ANZAC couldn’t do much and because of the massive build up in the Carolines they were quite scared and put their IPC in defensive troops.
In my third turn I had the luxury to only concentrate on the Brits (and China). ANZAC wasn’t posing a threat and the US wasn’t in the war yet. So I destroyed about two thirds of their fleet and captured Hongkong and Borneo. It did cost me some ships. After that I was slowly advancing in the Dutch Indies and invaded New Zealand from the Carolines. I played a cat and mouse game with the US, so they never got to a full assault. My Caroline fleet was too powerful (largely because of the airbase with at least 6 planes sitting on top of it).
We ran out of time so we decided that the last major sea battle would decide which side won. The British fleet (BB, CV + fig + tac, sub, DD, CL, 2 bom) fought my western fleet (2 BB, CV + 2 fighters, tranny, DD). I won with a damaged BB left. By that time I also had all the Dutch Indies and all of China. And none of the allies had any NO.
So I won that one too, so it can be done, of course. Although I don’t what would have happened if the Brits hadn’t attacked and had another turn of a large income and captured another Dutch island.
