SummaryJack-of-all-trades, master of none
The GoodThe chance to fly 40 different aircraft, including some uncommon-for-flight sim ones (like the X-15, F-5, Mirage F1). The range of missions - recon in an SR-71, tactical bombing in a MiG-21, long-range intercepts in a MiG-25 or F-14. In-flight refuelling. Shoot down enough of your side's aircraft, and you'd defect to the other side.
The BadThe graphics were a bit poor, the cockpit was dreadful, and forget about the sound. The vast range of aircraft and weapons meant that the couldn't all be modelled accurately.
The Bottom LineA good game for flight sim newbies, but it just doesn't have the grunt to be a decent flight sim, even back in '91.
