Polybius is an urban legend videogame–meaning a video game that is only rumored to have existed.
BA: Polybius is a video game, supposedly made by SEGA, that caused the kids to play it to have seizures. They say there’s only been one Polybius cabinet–this was the 80s, when games were in cabinets in arcades, like Pac Man and Asteroids and stuff…and this cabinet was in Portland.
Why was there only one cabinet?
BA: There was only one cabinet, because that’s how they tested the game before release. It was a big game by a big company, and it used new graphics technology, so they just secretly tested it under a fake name…if the game passed testing, it wouldn’t be called “Polybius”. But… the kids who played it got addicted to it and had seizures. People reported seeing men in suits watching them play, and some say it was the United States government watching to see the effect of the game, to somehow use it as a weapon. Anyway, they scrapped the game and hid it from the records once the kids had seizures, so they couldn’t get any bad press, so nobody’s heard of it since.
The mystery of Polybius originated on the internet in discussion boards in 1998. It’s since snowballed to a huge essential question: “Is Polybius real or fake?”. Some claim that it is a fabricated story based on the overwhelmingly negative reception of the early testing stages of Tempest, while others claim to have been part of the developer team responsible for the game.
There are some slight references to Polybius in popular culture, such as a background joke in The Simpsons and the plot of a long-cancelled G4 series, Blister
