@mozkaynak I tried this on a Pacific-only game a few weeks ago. Basically, Japan took out most of China (Me and UK/Anzac were working together but he isnt the best of players…) Yunnan was taken round 3 and soon, South East Asia was under threat. As the US, I joined the war round 3 and immediately moved into the Caroline Islands. The Japanese already evacuated the islands in response to a possible threat of their mainland islands. Fighting continued and I island-hopped a bit, helping ANZAC along the way. I think it was around round 6 or 7 when I setup an epic trap for the Japanese player.
We are playing with DK’s research board so the US had Super Subs (lucky me!) and so I spammed transports, lots of subs, and the occasional tac and fighter (it depended.) I strategically placed my units in a way where the Japanese player did not understand where I would go. The destination: take out the Japanese home fleet and capture Korea. I used a bunch of planes scattered around and some ships, taking the home island zone fairly easily. The reason why was because he didnt think I would attack there.
There were some problems before that however. The caroline island fleet got destroyed by a Philippines build-up of the Japanese player. This limited both of our naval capabilities for another 2 -3 turns. India fell probably around 7-8 rounds in and the Japanese player looked for Sydney to collect that final VC to win the game.
The north of the Pacific looked pretty good for me. The money islands were mostly secure until the ending of the game where Japan with what navy they had left sailed towards Sydney. I had taken Korea and then I think I took Manchuria and that stuff. Japan tried building a fleet in Shanghai but I blocked all of his coast line and cut him off. In our games, we dont do convoy raiding sometimes just because it makes the games more complex (but I think after our Europe game we will do it) If you block a sea zone with a factory, if the seazone is blocked by an enemy you cannot build. Anyways, the game was a stalemate and we ended it idk I think round 11.
