I think that we need some good pre-90's campaigns for most aircraft but especially the M-2K. I am growing tired of all of these "kill the insurgents" missions that I keep seeing. We need someone to make a good full scale air war scenario against aircraft of comparable capability.
It would also be interesting to see the campaign built around interceptions rather than achieving air superiority. Interception is, after all, the original purpose of the aircraft, not killing everything in the sky.
