Here' another good debate spawned by Levi Kornelsen on RPGnet. I think that the back and forth between the two "sides" of the discussion shows that there is a lot of inflexible thinking that is going on in these debates, and an unwillingness to deviate from the party line. I hope that something good comes out of this because (although it probably really doesn't matter overly much) I really like Levi's line of thinking and I have since he started along his current path of "theory."
Plus this thread features some of my favorite thinkers from RPGnet (besides Levi): Marco and Balbinus.
