Yes, to a degree I know that one does exist. You can chose from quite a broad selection of maps and scenario's and then choose how the opposition is made up. (and that is actually quite a lot and actually really quite easy to achieve compared to some other air combat type things that I play)
But what if it was just one step further?
Be able to choose sector types and placement on map? Be able to place random ground target objects?
I'm just gonna leave it at that for now...
