A near perfect game would be a blend of the BF series with the AH "Sim" aspect.
The WWII mod for BF Nam, and even BF Nam itself, accomplish the FPS / air combat blend very, very well. Esp the BF Nam maps with the "Sandies" Skyraiders. Once you bail out you hit the ground running / fighting, after of course causing hate and discontent on the ground.
The BF1942 Coral Sea map is almost a pure air combat map, only after getting shot down you can sneak into a sniping position and pick off pilots waiting for planes to spawn on the carrier... or if youre real sneaky get onto the carrier itself and knife / shoot / nade and otherwise cause havoc. Of course they will then chase you around.
The air sim aspect of the BF series is weak, at best, in relation to AH tho...
A blend of the two, ahhh...
