"Critics who treat adult as a term of approval, instead of as a merely descriptive term, cannot be adult themselves. To be concerned about being grown up, to admire the grown up because it is grown up, to blush at the suspicion of being childish; these things are the marks of childhood and adolescence." - C.S. Lewis
People need to stop using the word "fanboy" in arguements. It makes you, and all gamers, look bad.
