It is not true that most of the USA resources went to the pacific. During the war, it was more like 25% and 75% for the war in europe, following the europe first strategy established at the arcadia conference in december 1941.
As late as december 1943, the proportions between the pacific and europe were very even, approx. 1.8 million soldiers each, 7,800 to 8,800 aircraft and 700 to 500 ships. At the end of the war, 47 divisions were in action in europe, while in the pacific, there were only 21 plus 6 marine divisions. It was certainly only in the naval sector that most capital ships were deployed in the pacific.
In general, the americans had undertaken an enormous buildup from the start of the war. They managed to reduce the construction time of an aircraft carrier from 42 months in 41 to 32 months in 44. this also shows that most carriers were laid down in 42 in order to be available in 44. I'm looking forward to seeing how this is implemented in warplan pacific.
To your previous question about an invasion of north africa. Such a large-scale invasion took a long time to plan. It took the allies a year for normandy. The americans simply had not yet produced enough landing ships, equipment, or soldiers. Most of the equipment was provided by the british. Therefore, they were not ready until november 42.
By the way, i think warplan is the best WW2 game of its scale so far. You are doing a great job and the discussion is just about nuances on a very good developed game.
