"Su-27 Flanker was a runner-up for Computer Gaming World's 1995 "Simulation of the Year" award, which ultimately went to EF2000."
"PC Gamer US nominated Flanker 2.0 for its 1999 "Best Simulation" award, but it lost to MiG Alley."

Hmm. What did EF2000 and MiG Alley have that 'Flanker' still doesn't have after almost a quarter of a century?
