Germany: get rid of the Panzer. Replace it with a UB representative of German production or intellectualism. The UA needs to be scrapped and reworked altogether. Japan: scrap the Zero. Replace with UB. There's more to Japan than just war-war-war. IMO, those are the two most pressing ones. America is outshone by the Shoshone, though. I think America could use a tourism-boost late game. Perhaps bring back the UB "Mall" in another light.
