That was excellent. Ahoy is quickly becoming one of my favorite YouTube channels, mostly because of the impressive amount of effort put forth in each video. Same thing with Guru Larry (who had a brief cameo in this one)...their videos always have quite a bit of substance to them.
Polybius always seemed like a story that was too good to be true (not to say that a shadowy, brain-melting arcade cabinet is good, but I digress). And like this video touched on, the whole Polybius legend seemed to be cobbled together and inspired by other gaming myths and real-life events.
