I'd thought from the pre-release marketing that they said you'd manage taxes for everywhere at a single screen, with ability to micro-adjust individual provinces where you wanted to. Obviously not correct- as already pointed out, you can only exempt specific regions entirely but not micro-adjust. Just a misunderstanding on my part, I guess. As to theater-level taxes, I haven't gotten there.

I really like the overall tax thing, b'c province-by-province just killed campaigns as your empire grew. Still, it does make the game more difficult, b'c if you exempt newly conquered prov's to improve moral, it reduces econ incentive to go conquering in the first place!
