Polybius is an urban legend about a video game that appeared in arcades in the 1980’s around the Portland, Oregon area. It caused people to migraines, have hallucinations, hinted at mind control, cause knife attacks on others, and government conspiracies.

Like most things, if you dig in there is very little concrete evidence. Instead, it appears to be a collection of events that were all real and related to video games of the era.

The Why Files does a pretty decent job digging into the legend and gets a good collection of the facts behind the legend.

This one is definitely better than the fake documentary from a few years back – a reminder that documentaries need to be verified too.
