Hi. You could use Larry’s 42 set up. I have played that quite a bit on AAA with others here. You would probably have to play 3 times to see how much of an at War NO the US needs to compete against the Axis, without tilting too much in the allies’ favour.
Please report back how it goes playing Europe stand alone.
I don’t know if you play AAA or whether you would want to download it, but I attach a 43 version I set up and have played twice.
The axis cannot win and that was my intention. It was solely done, as I love playing Germany with its back to the wall, with the nasty Russians growing stronger and invading Germany proper.
