What Defines A Huge Video Game Fan?

In today's highly collectible installment of Speak-Up on Kotaku, commenter Korio8 wonders what the requirements are to be considered a "huge fan" of a video game or game series. What games do you consider yourself an above average fan of, and why?

How do you consider yourself as a "huge fan" of someone or something? Like video games.
Does it mean you have to own all the series in of the game and finished every single one of them? Or just all the games PLUS those official and unofficial goodies? Is there a standard of some sort? Just wondering =)
