However with all the serious talk aside and your excellent counter point in mind, you're really bringing down my crazy conspirator vibe. If you would just look closely at this picture of a UFO found by a 75 year old man who can't pronounce his own name, you'd clearly see them playing CoH on their super advanced computers run by cow bones.
In fact we see evidence for City of Heroes being played centuries ago. All over the world, the Mayans, the Inca, the Egyptians all built pyramid structures with significant geometric similarities. Now historians will suggest that these structures all had different purposes suited to their respective cultures, but Ancient Superhero Theorists believe that these were all build specifically for the purpose of enacting the classic City of Villains tutorial mission "Breakout." As further proof, many of these structures contain writing that refers to "the gods." But who are these "gods" that the ancient texts refer to? These "gods" or "superpowered beings" are all described as having fantastical powers and abilities, like the ability of flight, the ability to leap high into the sky, to disappear and reappear anywhere, and to cross vast distances in the blink of an eye. Historians and cultural anthropologists would have us believe that its mere coincidence that this is identical to the four travel powers in City of Heroes, but Ancient Superhero Theorists believe that those described as "the gods" were merely ancient MMO subscribers who in the days before modern computers were forced by publishers to be granted superpowers to allow them to properly experience the game.
The game we know today as City of Heroes is really mankind rediscovering this lost knowledge that ancient peoples once possessed, before cancellation forced these megastructures to be abandoned and the superpowers to be lost.
