Sure, Dunsany may have influenced Tolkien, but Tolkien's popularity has been so great that much that came before him in the genre pales in comparison. I'd never even heard of him until this thread.
Wow. "Much that came before him in the genre pales in comparison." That's an awfully strong statement. I'm curious, how many pre-Tolkien fantasy novels have you read? For starters, check out The King of Elfland's Daughter by Lord Dunsany, The Well of the Unicorn by Fletcher Pratt, and The Broken Sword by Poul Anderson. All three are excellent books and all three are much more philosophically complex than The Lord of the Rings.
Oh, and even if you hadn't heard of him before, Lord Dunsany has had a
major influence on modern fantasy. Most of the landmark fantasy authors of the 20th century have considered him a prime influence. He might not have had as much mainstream success as Tolkien, but his influence on the fantasy genre is enormous. Without Dunsany, Tolkien may not have had the proverbial "shoulders to stand on".
Moorcock created Elric to be an answer to Tolkien - if that's not influence, I don't know what is. Besides, while Elric has companions, he was the star of the show in his books, which is also the antithesis of D&D, which is a mixed race group of adventurers, not one star and a supporting cast.
Actually, Elric was an answer to and the direct antithesis of Howard's Conan and the many copycats Conan spawned. Moorcock was an editor for a sci-fi and fantasy magazine at the time he first created Elric in the 1950s. He was sick of all the muscle-bound barbarian stories that were being submitted, so he wrote about a sickly albino sorcerer instead.
Also, Moorcock wrote a book called Wizardry and Wild Romance. It's a history of the fantasy genre. In it, he talks a lot about his influences. It's clear from the book that Moorcock basically considers Tolkien's books to be a waste of time.
Everybody had influences that came before them, but Tolkien's impact on the genre has been so great & so popular, that everything that has come since has been touched by his works in some way.
Yes, but that's like saying that every sci-fi story that invovles space travel was influenced by Star Trek... or Star Wars... or Battlestar Galactica... or Buck Rogers... or Flash Gordon. If you set the bar low enough, then yes, you can find influence everywhere.
...Getting back to D&D....
Look at Appendix N in the 1e DMG. Gygax lists the literary influences of D&D. Tolkien is listed, but there are a lot of authors listed that pre-date Tolkien or were his contemporaries.
Then there's Dragon Magazine issue 95, pages 12-13. Gary Gygax wrote a two-page article entitled "The influence of J. R. R. Tolkien on the D&D and AD&D games". Here are a couple of quotes from the article:
"The popularity of Professor Tolkien'’s fantasy works did encourage me to develop my own. But while there are bits and pieces of his works reflected hazily in mine, I believe that his influence, as a whole, is quite minimal."
"A careful examination of the games will quickly reveal that the major influences are Robert E. Howard, L. Sprague de Camp and Fletcher Pratt, Fritz Leiber, Poul Anderson, A. Merritt, and H. P. Lovecraft. Only slightly lesser influence came from Roger Zelazny, E. R. Burroughs, Michael Moorcock, Philip Jose Farmer, and many others. Though I thoroughly enjoyed The Hobbit, I found the 'Ring Trilogy' . . . well, tedious."
