So the Japanese side should face the much better ones they didn't have to face in reality?
Seems like everyone wants to bend over backwards to make it easier than it already is for the US in US vs Japan settings.
Errr...no...the point I was trying to make is that the Brewster modeled in the game (the B-239) is NOT the model that faced the Japanese so it probably is not overmodeled and really shouldn't be used in Japanese vs. Allies scenarios. The model that faced the Japanese had a different designation and is not modeled in the game. Anyway, with the exception of Midway, the version of the Brewster that fought the Japanese mainly fought against the Ki-27 and the Ki-43, neither of which are modeled in AH. If you're going to demand that HTC, for the sake of accuracy, model the version of the Brewster that fought the Japanese, you should also insist that HTC also model the Japanese aircraft that most often fought the Brewster. Otherwise, in US vs. Japan settings, the Japanese would have it much easier than they did in real life (assuming that the Zero is used as a Ki-43 substitute).
Besides which, I'm not sure if HTC would get a lot of mileage out of modeling a version of the Brewster that was a bit of a pig, even when the British, in desperation, replaced all the .50's with .303's to reduce weight and try to squeeze some more performance out of it.
