Polybius

I had never heard of Polybius before – it sounds a bit like a real-life Lucky Wander Boy:

[A]n unheard-of new arcade game appeared in several suburbs of Portland, Oregon in 1981, something of a rarity at the time. The game, Polybius, proved to be incredibly popular, to the point of addiction, and lines formed around the machines, quickly followed by clusters of visits from men in black. Rather than the usual marketing data collected by company visitors to arcade machines, they collected some unknown data, allegedly testing responses to the psychoactive machines.
