Well decided to start my first game as USA as a nice easy game. Not digging the neutrality system at all. The undeclared war sounded cool in the dev diary, I need 40 threat with Germany to activate the decision, I currently have about 1% threat due to different continent. This is in late 1941 when Axis controls pretty much all of Europe besides a few hangers on and the UK. My highest threat is Japan at 16% due to different continent. They ate up China and hangers on and took over French Indochina. I know the US is isolationist, but this is kinda silly. At this rate I won't be in the war until 1944 or something like that. Having the fall of France neutrality losing decision be linked with Yugoslavia seems odd when in every game I have ever played of HoI3 Yugoslavia never gets involved in the war beyond offering military transit rights. So that is a big chunk of neutrality I will never get to get rid of. I'm very much not impressed so far.
They get some decisions that lower the neutrality massively if certain things happen like the fall of France and such, very nice IMO.
