D&D was fun.
In D&D I mostly play assholes, yet in most role-playing videogames such as Mass Effect or Fallout I play the hero and try to do the right thing. Maybe it's just a lot more fun in D&D to play the asshole, or perhaps it's a part of me being let loose. The part that wants nothing more than to be a dastardly supervillain and take over the world.
