I'll admit I'm a new school D&D player/DM. I've never discounted a player idea in osr or 5e, but I still wonder. Dwarves, elves, halflings... and so on.
Why do people chose these races?
To me, elves and dwarves are just humans with some tokrm magic element. Turtle people, and cat people and demon people and dragon people seem like a fun experience. Why playa dwarf and not a mountain dwelling human miner? Why wood elves and not tribal forest dwelling humans? Wealthy human wizards instead of high elves? I mean are humans even relevant in D&D anymore?
Is it a role-playing thing, or just a ability bonus power-up thing? I don't think I've ever ran a group that had a single human in it.
Tolkien has enjoyed enormous popularity for a half-century now.
Consider this: Led Zeppelin, the greatest rock band of all-time (pipe down, grognards! Zepp is better than the Beatles and that's just the gods' honest truth), peppered their lyrics with Tolkien references. Battle of Evermore, Ramble On, Misty Mountain Hop, Over The Hills And Far Away, and arguably "Stairway To Heaven" all contain references. The gatefold of Led Zeppelin IV features Gandalf and his quote "Not all those who wander are lost." At the same time, prog-rockers Rush put out "The Necromancer" and "Rivendell", two more Tolkien-inspired songs, while Sabbath had "The Wizard."
So, at a time when the biggest rock bands were at their zeniths, D&D was born, followed shortly by the animated TV movie "The Hobbit" (1977) and the Ralph Bakshi animated "The Lord Of The Rings" (1978) On top of that, magazines like "Heavy Metal" were finding their niche, and as artists like Jack Kirby were melding sci-fi, psychedelia, and fantasy, folk like Moebius and Frank Frazetta were laying down the foundations for cyberpunk and fantasy in art.
Tolkien was propelled into the zeitgeist through rock and stayed there for a solid decade, fueled by the 70s.
