I grew up with the Nam stories my dad told me, and I always wanted to fly the F-4, and then the F-8, then I saw flight of the Intruder and that got me hooked. An A-7 would be a nice addy. Also I think the soviets need to have a few more quality aircraft, so adding some later 70's a/c for them wouldn't be a bad idea. Also the F-14A would be a nice add.
But primarily I would like to see the whole late 60's to mid 70's USN aircraft list in the game. I think the F-8 is a must right now for air to air, because the F-4 doesnt stand a chance in a guns only or in close fight with a mig.
So in short, SF needs to stay with its time period, and LOMAC needs to add 20th century AMERICAN carrier ops.
