, if you believe this website
, was a video game developed by the CIA (or some other shadowy government organization) back in the early days of video games, 1981. But the game was really a secret experiment in behavior modification. Only a few of the game machines ever saw the light of day. They appeared in a few arcades in a suburb of Portland. Kids who played the game reportedly suffered disturbing side effects. They "woke up at night screaming, having horrible nightmares."
Some later developed amnesia. Occasionally black-coat types would come to collect 'records' from the games. So did Polybius
really exist, or is it all a hoax? Here is a rare photograph
of one of the Polybius machines (or perhaps it's just a modern photoshop). Even if it is just a hoax (which, yeah, it probably is) it still makes a pretty good story. (Thanks, Rob).
