A different type of oddity

I recently came across a local "Urban Legend" about a video game that was released in limited Portland suburbs. It was created in 1981 by a company called Sinnesloschen which is German for "sense deletion". It was a shooting/puzzle game.

The game was called Polybius.

It was apparently popular, people waited in lines to play it. People who played it experienced weird things while playing
such as hallucinations, nightmares following playing the game, nausea, headaches, blackouts and amnesia. It is rumored some even committed suicide. The game caused people to stop playing video games altogether. The owner of one of the arcades that had the game claimed men in suits would come to collect data or "records" from the game. The men in suits never collected money for renting the game to the arcades, they just came in and collected data. It is rumored that the game was a government experiment possibly in subliminal messaging. it remained out for one month, and then every arcade game suddenly disappeared. I guess one arcade had it reappear in 98' but disappeared again shortly after.
