For me - lightning simulator (1988) a little beauty of coding - a fully analogue keyboard control for a flight simulator, with gun-camera that automatically recorded 30 frames of 'tracking shots', 'worldwide' VOR, ILS, IFR, limit speeds, g-limits, multiple aircraft configurations, day/night progression, recognisable aircraft to practice dogfighting with/intercept. The 'war' mission was "challenging", being the interception of two single Backfire raids, escorted by two MiG23. And all inside 48K. Still fire it up from time to time.
Any chances for a game video?
