So you are saying that 3E/PF cannot do Gygaxian sandboxing? Because that is a playstyle in which the GM is not the final arbiter of events within the game.
You're understanding of Gygax's philosophy of play and my understanding are very different. I think Cadence demonstrates quite well from the DMG that Gygax believed that the DM was the final arbiter in the game Gygax designed.
Gygax believed that the closer one adhered to the framework of the game, the better the game would represent a true test of the player's skill, a philosophy I happen to agree with. Gygax also believed that there would be times the DM would need to go beyond the rules and that the DM had the authority and power to do so. I agree with that also.
As I posted earlier, and I don't think the quote or the thought therein is original to me: "A bad DM ignores the rules completely, a good DM uses the rules, and a Great DM knows when not to use the rules."
