Well .. I have some 'anecdotal' stuff .. I had a chance to fly the F-16 simulator at Nellis for awhile.
I also spent more than a few hours in the F-4 sim at various bases I was stationed at here an there.
I had a chat with the tech rep guy for Falcon *the game* long ago ..Pete (a Guard F-16 pilot when I met him).
I told him that I had flown the game .. compared to what the actual sim would do it was night and day.
He laughed, said there was no way they could make a game that would match real world figures or even come close.
I told him they did a great job of makin an F-16 feel like a Thud ..F-105 .. it took forever to get off the ground and vertical perfomance was terrible. -shrug-
.. also had a long chat with an F-15 pilot a couple years ago.
He said it's the Ferrari ..whereas the F-22 is just so much a step up that those guys have to use a stripped down F-15 as primary trainer ..the entry level air combat platform ..like the AT-6 was to the Mustang
Go to any airshow that has an F-16/F-15 flyin, granted they aren't carryin full loads, but .. you can see what they do.
Can't do it in a sim/game that I know of.
As for comparison to Soviet gear .. there just isn't any.
Orders of magnitude difference.
They are lead sleds.
There hasn't been an opponent aircraft that is a match for the F-15 built yet, altho they are closing the gaps, slowly.
But .. that's just my opinion based on what I learned over the years from the guys I talked to, things I saw, read, did, here an there.
