I submit to you that Dungeons & Dragons, The Original Boxed Set, is Amber from The Chronicles of Amber series by Roger Zelazny and all other RPGs are shadows of this original. Some shadows are closer to the original than others, but all can trace out their heritage to the OBS.
The question than becomes: If D&D is Amber, than what is the RPG based on the Chronicles of Amber. Is "Amber the RPG" itself The Courts of Chaos?
