I was thinking that a time limited application of weapons to aircraft could bring even more realism. For instance guided/heat seeking missiles would not have been seen on say Spitfires or Mustangs in their heyday. I am thinking along the lines of block periods eg. 1900-1940, 1941-1960, 1961 to present. This is, of course, a very loose set of parameters and could be adjusted as you see fit.

It is just a thought, however it may be unpopular with those who don't care for realism too much and find happiness in shooting rockets from their Wright Flyer. Perhaps this may be too much of a restriction. But it is a thought, nevertheless

Regards.
