FOO FIGHTERS! (the N1k dont glow yet)
I think all AH needs is more in-depth strat stuff. Supply lines, supply trains, aircraft factories, etc. If a country's ability to sustain itself, be it aircraft production or supply could be bombed out, it would make the game have a lot of new perspectives.
Imagine it. 1 Aircraft factory per every aircraft type in the game, ammo factory, aaa factory, grunt factory.. a supply network that takes the goods from those factories to the HQ and then from the HQ to all other fields of your country.
When you capture an enemy airfield, the supplies to that field will be airlifted or trucked over from the nearest of your country's bases (imagine the horde of AI/human flown C-47's and trucks supplying a base). Capturing an enemy factory will make the c47's and trucks go to your fields instead of the enemy's.
So you attack an airfield and blow out its hangars and AAA...and then you fail to take the field due to enemy CAP. The field will need to receive supplies in order to rebuild, and those supplies come by train or truck or c47 or all 3 combined. Now THATS something players can HIT to prevent the field from rebuilding.
Oh well, I can dream..
