3. Get The Triforce - The Legend of Zelda: Ocarina of Time
As any big Legend of Zelda fan knows, in the majority of the games, you end up being gifted the ellusive Triforce sooner or later, the world-saving device that Link is always after. Nintendo are in part responsible for this rumour given that early footage of Ocarina of Time did show Link getting a hold of the Triforce, which set the fanboys off on a feeding frenzy, one that was not really sated in the final version of the game. It wasn't long before rumours spread wild that if you performed an ungodly number of tasks in a very specific order around Hyrule, the Triforce would be yours to own later in the game. This is one of the most persistent and memorable video game rumours because it was backed up by video evidence, and while we didn't all have the Internet and YouTube back then, the footage was frequently shown on TV video game shows (ah, remember them?).
