Why am I not surprised that the majority of a video game forum is somehow introverted.

Anyway, I am Extroverted and Pessimistic... although I'd just call that realistic.

Videogame sales are even a niche in the videogame community. So considering that I am surprised there are so much extroverted people on this site.
