Heh, I was looking forward to seeing this one.
I'm an MMO player myself, but I'm not overweight or anything...well, I do have a slight acne problem. Anyway, I'm considered a pretty cool person actually, I even surprise myself how popular I am when I see five or more walk by back to back and each one of them calls out my name and/or gives me a hug/handshake. Sure it was stereotypical, but it was all in light humor and served its purpose of being funny. SkinnyNinja420 pretty much hit the nail on the head about the stereotyping issue, so I won't repeat it, mostly due to laziness.
