We’ve added a one-URL download for the entire contents of the IF Archive.

(That's not the URL, that's a post *about* the URL. I'm not about to put a 30GB download link in a social media twoot, good grief no.)
You might want to be aware of Club Floyd, in which people play IF cooperatively via a MUD (without really using any features of the MUD that aren't present in IRC). https://www.ifwiki.org/ClubFloyd is a good starting point to read about it; I think it's still active.
The reason I mention that is that they have similar requirements to what I'd expect a screen reader user would want, or possibly somewhat stricter ones. That said, the standard approach there is that this does restrict the set of playable games.
