I created the D&D game to sell, to get to as many consumers as possible, and the best way to do that was to include races that were favored by the many young Tolkien fans. Dwarves are hardly a main feature of the Rings trilogy, but hobbits, elves, orcs, balrog, and ents (the Anglo-Saxon word for "giant," of course) were. So I included them so as to sell the game. Even though I find the Rings trilogy a bore, found Bored of the Rings great sport, so what? Gamers are able to enjoy their D&D campaign with as much Tolkein flavor as they wish.
