Honestly I’m way more sad how little people recognize how insanely influential he is in fantasy. A lot of fantasy (and fantasy gaming in particular) has way more in common with Howard’s Conan, then LotR (well, besides the elves, orcs, dwarves coat of paint), yet even fantasy fans constantly forget about Howard.
Already answered it above, but - to really understand how bad it is is the answer. It’s pure shit and the books talking about it usually lift it up a couple of levels of quality.
