This guy didn't realize it, but he proved that "Fantasy" and "Science Fiction" ARE FAKE GENRES!
TLDR: All that changes are the trappings and the setting. The narrative structure is IDENTICAL so they play out EXACTLY THE SAME WAY!
This is why Andre Norton and Leigh Brackett can write "science fiction" that is really "fantasy" with a bare whiff of justification for the tale's telling: they are both doing Fantastic Adventure fiction, same as Burroughs, Meritt, Moorcock, Howard, Smith, and everyone else in Appendix N.
It's also why Shadowrun is just D&D With Chrome & Guns; changing the trappings and the setting didn't change the substance of gameplay one damned bit.
Dune (and its knockoffs, 40K and Fading Suns) is just a resetting of The Sabers of Paradise (go look that one up).
Star Wars (the original) is The Hidden Fortress plus The Dambusters.
Never, ever mistake a Product Category for a Genre; the former is a Brand Name thing, while the latter is all about narrative structure- seeming vs. substance.
"Fantasy" does not exist. "Science Fiction" does not exist. There are other fake genres; they also do not exist.
