Well, it isn't that Hungarian and Gagalog speakers don't have a concept of "gender" in social or biological terms, they just don't decline nouns the way Indo-European languages do. Some other languages decline nouns with completely different genus categories than social or biological gender: the...
That's a pretty good list...to be ludicrously complete, one could add as you say 4E Essentials (which kind of lives in a strange offshoot world like BD&D?), the refreshes for "1E" and "2E", and the final "Black Box" edition of Basic...but I think that even may be missing something.
Not quite how it squares in my mind, though I think that is a reasonable list, too. Main thing to me is that pretty much any attempt to clearly enumerate the variations of first party D&D (let alone the myriad variations of actual D&D!) is a fraught exercise that is going to be mostly based on...
Well, I lead with the caveat that I am not including OD&D or anyBasic, so that my list is also absurd. Just counting all versions of first parrt D&D I think I came up with seventeen distinct variations.
But for ninth, I am sticking by a more traditional publishing understanding of the term...
English is, per usual, very peculiar. Languages like Hungarian or Tagalog that have no linguistic gender at all don't have this situation, and in highly gendered languages like Spanish the conversation is entirely different. English only cares about Gender in the weird corner case of pronouns...
I did not say Gygqx particularly succeeded, but hey, it was a first try., let's give the guy a break. Yes, he got the hit points mechanics from existing naval combat wargames...nit he chose the mechanics intentionally to simulate a certain sort of Sword & Sorcerery story.
To be honest, I saw that as a bit of a mksstatementof the thesis, because classic D&D is focused on narrative genre emulation...of classic Sword & Sorcery tropes.
I think there is something to that: Cosmere in particular is very familiar in terms of the player side process, but the structure provides a very different experience focused on more narrative oriented results and play loops.
As someone who has had to do written customer support for customers with names that I had zero cultural context to even make a guess at their gender...gender neutral pronouns are an absolute necessity for polite interaction.
