Ok...I had better contribute something here, having complained loudly! I would not change anything to do with the technical aircraft simulation side of DCS: the technical rendering of the aircraft is, IMHO, generally superb. It is the supporting 'framework' that needs work. I would like to see, as my wishlist, in order of priority:
1) A dynamic, cogent and persistent campaign in which to fly these technically superb simulations;
2)
