Thank you for your patience, Thor.
I think that we have enough flyable planes to make any conceivable campaign or mission, save for the heavy bomber, that are ill suited for the game engine. I feel that we actually need some more AI types. Correct me if I’m mistaken, but AI types are much less complicated to do than flyable ones. If – just an educated guess – four AI types require as much work as a single flyable, I would surely choose the four AIs. An example: instead of the G**m**n A**n**r, I would prefer the complete series of Navy types on carrier deck: Devastator and Vindicator for early war years (needed to recreate Midway) and Helldiver for late war years (needed to recreate the Leyte Gulf battle). I repeat: AI only!
But, of course, to ask is easy, and we must be grateful to DT for anything they had done and will do in future!
