I freely admit that half the reason to ask is because of how poorly the ground combat works in AH2. The normal engagement ranges are ludicriously long, usually well over a kilometer or even 2. That doesn't seem to jive unless you are talking about North Africa.
I agree that for flight sims the terrain doesn't need to do anything other than kill you if you fly into it, but I still think a good map would be better. Nothing, and I do mean nothing, compares to AH-2 for air combat PvP. This is THE flight sim I compare all others to on how well they play, and for customizable controls. Nothing beats the stick set 1 to stick set 2 changing on the fly. I can't stand other flight sims that won't let me use my hat switches in two modes at the push of a button to get the 45 degree up views.
I play Planetside 2 right now, but I HATE their aircraft with their mouse and keyboard controls, and you cannot look around and steer at the same time. Yet, we also have ground combat in AH2, but the terrain lets it down severely.
However, even if a newer map style was introduced, I doubt it would be on par with current games like my other favorite flight sims like Rise of Flight (awesome WW-1 flight sim for those who never tried it, go get that demo version with the Albatross and Spad and see). But, if it can be improved, I want it to be improved.
