There's the kind of unrealistic Jetfighter V: Homeland Protector which I haven't been able to get to run on windows 7.
Theres DCS A-10 and DCS Black Shark....
There's Flanker 2.5 which is like an older version of Lock On....
There's old DOS modern flight sims....
I'm trying to think here...
I don't know any more off the top of my head.
