How is that a problem? If you’re interested in a subject, you learn its terms lol. It’s like saying “checkmate” is exclusionary because you have to explain to someone who’s never heard of the term or played chess what it means.

If you’ve never taken or cared about literature, how are you supposed to infer what “first person shooter” or “third person sandbox” means without reading about it or having someone explain

If you don’t explain to someone what anime is then you shouldn’t surprised when they ask if you’ve seen the new cartoon about robots fighting each other

A valid genre complaint would be something like Tyler the Creator being labeled as “urban.” It doesn’t mean anything except “the artist is black and makes music people dance to.” It’s not comparable to “country” because that has distinct features outside of “white people singing about farms”. Describing a game clearly uses mechanics inspired by or pulled from From Software without mentioning dark souls would be disingenuous - unless, like the OP said, there’s enough variety that referencing the original game doesn’t make sense. Most rock bands don’t mention the Beatles anymore despite their innovation.
