I'm going to be honest with you Ian, and I hope you would do the same with me, that some of your posts in this thread do quite seem like you're talking past people. In your response to the post that you linked, for example, you said: "I would need a strong argument to convince me that explicit guidelines, rules, and mechanics would serve a game like D&D by being included in a core rule book." I can't find anything in Sandy Pug Games' post where they implied that they would. I can find points where they said "properly written rules can contain [those concepts]" or that D&D doesn't have those concepts, but nothing about D&D benefiting from having those concepts in a core rule book. Did I miss something in the post?
