Quoted from SealClubber:I'm not saying it isn't fun, it is. But I seem to remember reading an interview somewhere that AFM was indeed meant to be a low build-cost game. The saucers are just a cheap mold with a flasher dome in the middle. The Martians are basically just a coil and a plunger which were used in Elvira and SS. The 3bank target was used in BK2K. It had all stand up targets and an open fan layout with two flippers that isn't cluttered with useless shots put there to just fill a space. IMO, it was the humor and great theme and art package with an easy to understand ruleset that made it a winner.
... and the 3 bank targets on BK2K are just a cut down version of the visor targets on Pin*Bot. The alien targets still have controlled solenoids that easily could have been just figures mounted on a spring bracket. Lots of features on some pins are "Borrowed" or re-purposed on other machines. That doesn't make a game necessarily cheap.
