It's not Lord of the Rings or Conan.I don't think Gygax was trying to do Tolkien style world building at all. I do think others who followed and put out stuff for D&D were leaning heavily into Tolkien but a lot of Gygaxian D&D to me really fits those Conan stories. One key difference is Gygax seems to be aiming more for a medieval vibe than Conan (and Conan was more pre-historical Ancient World kitchen sink).
OD&D is Lankhmar. It is shocking the first time you read the early Lankhmar books -- they could be official TSR D&D novels.
