I play all kinds of games and systems, its easy to find one I like the feel of mechanically. Phoenix Command for grit and trauma, Munchkin for lighter fare, and many in between or off of the scale entirely. And I like all the editions of D&D they all have something interesting. So the specific rules for DDN don't really matter that much to me.
What is important to me is that DDN may bring a few more people into the hobby. While I'm comfortable with Apocalypse world or Slam Puzzle or Lamentations of the Flame Princess those games are certainly not for everyone.
My hope is that DDN can be for anyone. What is your hope?
