Me: This is madness!
Players: THIS IS D&D! <kicks me down the hole>
I learned a very, very long time ago that D&D is good for running one game, D&D. That's fine, because it's very, very good at running D&D games. I kind of get the feeling as though the rules are designed to run D&D games. The rules aren't very good for diverse settings outside of it's own tropes and I came to that realization way back in 1991 when I foolishly attempted to adapt the Wheel of Time to 2nd edition. That D&D divides magic into the Divine and the Arcane is just one example of how ill suited the rules are for fantasy settings other than D&D. Attempting to adapt D&D to other non-D&D settings is a lot of work and you'd be better of with GURPS or some other system. i.e. It's a fool's errand.
Granted, this is just one person's opinion. And if it has offended you, remember it simply as a dream. That you have but slumbered here while this vision did appear.
