Those kinds of crashes baffle me. Good luck, Dale!
By 1936, Europe's been developing for centuries longer than any of its colonies. So could you make some basic sort of building or something to represent that development, prerequisite for all factories? And make this "Development" building take a crazy long time to build. Only developed cities would have it, and developing colonies or other small nations would almost never be able to get it built, and that would represent accurately and effectively the big development difference.
Japan's mainland could have these Development buildings, but (I think) China shouldn't, and that would make a big difference. Planes can be expensive and Japan can lack oil early on, but still they'll have that huge industrial advantage over China (and that's realistic, isn't it?). As of now, when I play as Japan I'm able to use Great Engineers to really beef up the production on Japan's scattered Pacific islands, but that doesn't seem right. The islands should be little more than indestructible aircraft carriers, shouldn't they? Japan's mainland should be the main factory that has to fuel everywhere else, right? And if it takes one of these Development buildings to make a place have any industrial capacity, then even Great Engineers on those little islands won't be able to do that much.
And this way, tiny Europe, Britain's main island, and Japan can all be much more powerful than sprawling China or Brazil, even if a human plays China or Brazil.
I think that's a great idea, but this building shouldn't be possible to build anywhere else because people can just hurry production on it with a lot of money.
It will also require units to be beefed up quite a bit in price.
To simulate the colonies supplying troops to countries, drafting units should be a possiblity again. This way cities without much production experience can still make units. How about they always make the unit one level less than the one you currently have. (can build advanced infantry, can draft improved infantry)
