Polybius

The arcade cabinet that took your quarters and your sleep, collected weekly by men in suits.

The Polybius legend — a 1981 Portland arcade cabinet causing amnesia and seizures, collected by men in black — first appears on a game database around 2000 with no contemporary trace. Documented seeds: 1981 Portland arcade raids (real, gambling-related), competitive-play sickness incidents (real, reported), and the era's genuine FBI interest in arcades. It is the archive's model synthetic legend: assembled retroactively from true parts, none of which contain the story.
