I've having some difficulties. I understand that taxation and production aren't tied together, but the relationship between production and allocation of production along Social, Military and Research isn't very clear. I can have production locked at a certain number adjust the allocation and get radically different results.
What would be better is simply three bars that go from 0% to 100% that are independant of each other along with something that locks them together up and down. It took me about 15 hours of play to figure this out which may be more than some, but since it wasn't what I was expecting this needed to be more carefully explained.
