I played Jetfighter on a friends PC in the late 1980s and it always struck me a game that was not sure if it wanted to be an arcade game or a flight simulator. So the learning curve, if you wanted to get good at the game, made you work. All in all I was left with positive memories, although I had not though of it until I spotted this ad. The series, which was initiated in 1988, was made by Velocity Development. It had a bunch of sequels, that stretched out, under other studios, well into the new millennium.
