No carrier based Georges. In fact, the Sam "Reppu" A7M was intended to replace the A6M as the principle carrier-borne fighter.
With the game the way it is, ppl using 47s with 1000lbers and a 500lber centerline to kill CVs and CAs, I wonder how much use D4Y and B6N would actually get. Probably the same reason why no one really complains about not having an SB2C.
I do agree, however, that there are gaps in the IJN, Russian, and Italian planesets.
However - since the Brewster broke some ground - there's a slew of aircraft that could be considered that came from smaller countries, or for whatever reason, have been neglected by history...IAR 80s, Dewotine D.520, Moraine Ms.406, Boomerang, Wirraway, etc., that fit the criteria for combat as well as some aircraft we currently have. Yes, its true, most would be FSO or AvA aircraft, would be hangar queens in the LW, but so are a bunch of planes we have now.
