Why nobody know Dsaf?

At this point, I think Fnaf fangames are underrated, cuz Everyone know What si Fnaf, but if mention something about the fandom they look at you like a werido (At least in my own experiences) And for me, is sometimes annoying that people think Dave is William or Jack is Henry, I know that are people that doesn't have to know all the things of each game, but when they name Dsaf as Fnaf and refuse to get corrected, is irritating ngl, more if they name themselves as fans that thinks because they know the lore, they're superior and I know fnaf community can be very toxic tbh, now with this, I really wanna try more fangames cuz I'm really curious and maybe I can try other games that can be good as the original, any recommendations? (srry if my english is bad, isn't my first language)
