Well, that's one of the most ridiculous things I've ever read here
But it definitely confirms my suspicion.
So, it's a fallacy that D&D isn't the best system for everything?
I guess, this is right opportunity for the saying: "if your only tool is a hammer, every problem looks like a nail."
I hope not to crush your version of reality if I tell you that there are places where D&D is not the market-leading rpg, e.g. here in Germany. In fact it's well on its way to sink back into total obscurity since it no longer has a German publisher (while Pathfinder does - but that's an entirely different problem).
I bet he also developed an excellent technique to drive screws into walls using a hammer

Have fun - I'm out!
