Destructoid: "As we all know, the one thing that sets videogames apart from other forms of media is interactivity. Being the catalyst for your own adventure is something that makes gaming more interesting to me than any movie or book. With videogames, one can stop being a mere passive observer and actually be a part of the action.
That said, if there's one thing I may have done more than playing videogames, it's watching videogames. Whether patiently waiting for my turn or being astounded by the skills of a superior player, sometimes it's more desirable to be a passive observer."
