Hello <---(new to the forum)
Much of what has been posted here makes sense. There is, however, another needed change that has apparently been overlooked. In the original WWII scenario that comes with Conquest, I noticed that both sides have to research Advanced Flight before building fighter/bombers. At the time of Pearl Harbor, the Japanese attacked with Zeroes, Val dive bombers and Kate torpedo bombers. The US had at the time Brewster Buffalos (on Midway), Wildcats, SBD Dauntlesses and Vindicator torpedo bombers (Devestators came out shortly afterwards). I was thinking of adding these myself at the beginning of the scenario. Then for the Advanced Flight tech adding Corsairs, Hellcats, P-38s, Helldivers and TBMs.
One other note, although I may be getting too technical here, is changing most of the US battleships to WWI Dreadnaughts, found under the Units Forum. All in the scenario were vintage WWI dreadnaughts. Although the Tennessee was launched in 1920 she resembled the WW2 battleship design (but with 14" main guns). The next battleship launched was the North Carolina in August of 1941.
Just a thought.
