I'm not advocating making minors as strong as majors, but the system right now is broken. It neither makes sense from a historical or gameplay perspective. Can you honestly say Germany building IC at a cost of .5 in one month works within the gameplay mechanics? Compiled with its early conquests and practical/theoretical values, researching and building things becomes ridiculously easy.Sorry, I do not agree with this. Why should a smaller nation be more effective is utilizing and learning from their projects than bigger ones? Germany produces 10 infantry divisions and through this process learns how to more efficiently produce future ones. Are smaller nations just that much more clever that they can learn how to be just as efficient with less experience? Germany has twice as many leadership points some minor nation and so German scientists half as clever as their smaller rivals?! Sorry not a cogent agruement for me.
Large nations have many, many advantages over small ones. It may not sound fair but it is reality.
On the other end of the spectrum, a nation like Canada underwent massive industrialization during World War II, and outproduced a "major" like Italy in most categories. In-game Italy has more than double the IC, and catching up is not possible given the limitations from weak practical values in construction.
Both of these extremes need to be brought closer to each other to make for better gameplay, both for fun and history's sake.
