Craig Perko riffs on Dungeons and Dragons the role playing game for not having enough role playing in it.

You need content, yes, but you have to remember that every game is communicating something. Every experience the players share says something very strongly. Having a million different things that could happen is pretty pointless. Instead, there are about two things that should happen, and they aren’t written down anywhere because your adventure is (I hope) quite unique. Anything else will weaken the experience, turn it into a slush of experience points and dice.

Right on.
