Hey Mr. Fork. Sorry if I was negative, myself I have asked for night time arena, barrage balloons, and other stuff that gets the treatment. You didn't say anything about it being opt in and this being an argumentative place with very few neutral opinions don't worry about the flak, its deeply impersonal.
My thing about AH2 is I feel like the basic balance between realism/playability is really the best I have experienced. Most flight sims seem to confuse realism with familiarity with check lists. That never feels real to me because the physical interface is a keyboard and mouse. On the other hand joystick, throttle and rudder pedals physically approximate to some degree what flying a plane is like. The best part of AH is the aircraft handling and the view system. For more realistic engine management I would want support for simpit builders, but those are rare as hen's teeth and I suspect that having data to drive instruments and multiple displays opens the game up to hacking.
I would not be surprised if you would agree that AH is at its best during special events, the dar, icon range, and death aspects of it make it much more involving, I can see how another layer of complexification might enhance that. To that end I'll see your engine management and raise you paper maps, clouds, a decent compass and hold the GPS. On the other hand that might be too much for most players and the terrain would have to get a little less homogenous for pilotage. (Probably cooler for the bombers than the fighters.)
