Polybius is a very-likely fictitious 1981 arcade game, allegedly published by the shadowy Sinneslöschen corporation and given a limited release in the suburbs of Portland, Oregon. It originated as an urban legend that dates back to February, 2000.
Storyline
The legend of Polybius is, as legends tend to be, rather amorphous, and there are many different versions of the tale. The main ingredient is the game itself, a seemingly innocent cabinet that popped up and hides sinister motives, from subliminal messages to more supernatural activities. Often, the game is described as playing like the 1980 classic Tempest, but sometimes the gameplay itself isn't actually described. Early versions depict Polybius as a vague government experiment, presumably related to mind control in the same vein as MKULTRA and similar experiments. Kids lined up to play the strange game, with mysterious men in black suits either standing by and taking notes on clipboards, or coming by after hours to collect the data direct from the console. Soon, the players started to experience disturbing symptoms — nausea, migraines, memory loss, nightmares, and in some retellings even "an inability to become sad". Many players swore off games altogether, with one even becoming "a big anti-video game crusader or something". Others portray the game as more outright malevolent and possibly alive, with spooky details like occasionally not requiring coins to play, continuing to work after being unplugged/shut down, and other creepiness. At any rate, in nearly all versions it disappeared entirely off the face of the Earth after only a month or so. Perhaps of note, the developers of Tempest are on record as saying that early versions of the game featured the tunnel spinning while the player's ship/lane remained in place, rather than the other way around as it was in the final release game. This was changed due to the spinning tunnel causing vertigo and motion sickness in some playtesters. If any test units of the early game were ever in public, or if talk of a "game that makes you sick when you play it" were to emerge from playtesting, this could be the kernel of mundane truth on which the wild stories were based. In such a scenario, the "men in black" / government agents would be nothing more than the game developers getting reporting data from the cabinets and feedback from the players for their game in testing.
