When I think of a video game fanboy, I think of someone who is typically ill-informed about gaming as a whole. They are usually the kind of person to troll a message board, debating to the break of dawn as to why a game on their platform of choice is the only version everyone and anyone should buy. They may even go as far as to say their exclusive title is better than another systems exclusive title.
In the case of this Kannagi episode, Akiba goes a little too far with the Sony love. How far you ask? Two simple words: Beta. Max.
