The problem with Korea in AW was that the G's weren't modeled correctly. Also, there were only two jets so the selection was limited. It was always one jet or the other.
But if the Cougar and Panther were brought in; and the Skyraider; and the Gloster Meteor; and the Twin Mustang; and the Sea Fury; and the P-80/F-80 Shooting Star; and the B-29 ... now you're talking a pretty sizable plane selection that makes things interesting.
And on the ground war side you'd have the Type 58 vs. the M24 Chaffee, M4 Sherman, Centurion, Pershing, and Patton tanks.
I'd rather see Korea than WW1.
