It’s rather funny because I’ve been thinking the same exact thing as you. Before I knew the official setup, I though Germany would have close to 20 aircrafts… I managed to work on the setup too and, based on the strength of the airforces in Europe (remember that Germany has only 8 aircrafts), I removed even more aircrafts from the Pacific map than you did. Now Japan “only” has 12 aircrafts (this is enough IMO), US 4, India 1, China 1 and ANZAC 1. In order to balance things IPC-wise, I had to remove 8 infantries in Russia along with a few other ones on the allied side. (Look on wikipedia: 5 infantries in Malaya is way too much when compared to the armies in Europe.) I’m gonna try this as soon as possible and see if it’s balanced (and fun…).
