The real question is: How DIDN'T it? I mean really - EVERYTHING
  you need is _right there_. Just... doesn't get any better than
  that. Interestingly, the creator of DnD was a Jehovah's Witness.
  Towards the end, he came back to it, although if you _really_
  think about DnD and what *isn't* there among all that is... he
  never really left it.
