Mmm, I think that probably must've been Flaming Cliffs. That's where you can fly SU25, SU27, SU33, MIG29, F15C,A10A... all with simplified flight model and not as functional cockpits as DCS-A10C or DCS-KA50. Only the SU25T has the advanced flight model I believe. The FA-18 was not flyable I believe.
