Note: Eight hundred and thirty years (and hundreds of mergers and aquisitions) after the "Dungeons & Dragons" property was aquired by Wizards of the Coast, Nectaris Nanotech acquired Crystal Coveyou, and the two companies ushered in the Third Age of Fantasy Role-Playing Games.
"Dungeons & Dragons" 16th Edition was made so simple and accessible that anybody could play it without source books, pencils or paper, character sheets, or even much imagination. All that was required was a set of dice.
They were, of course, very expensive dice.
