Neutral Good

A lot of games lately have a karma meter of some sort to allow the player to either be a hero or villain. I've noticed that most reviewers (and gamers in general), seemingly nice people, seem to gravitate towards being evil bastards. Meanwhile I, epitome of asocial bastardry that I am, seem to play as a paragon of justice and self-sacrifice. Are we all playing to our opposites? Or are dark hidden truths being revealed through our hobbies? Do we unleash the hidden jackass that we would never show in the real world? But then what of us who play the hero? I have no answers, but I thought I'd raise the question. And perhaps we can all ponder what our playstyles say about ourselves.
