This is a really interesting list.
Thank you very much for taking the time to compile and share it. I’m actually not very well-read (…uh, well-played??) in IF, so I don’t think I’ve played any of them, but have certainly heard of some of them. Violet, especially – I’m incredibly surprised that’s a one-hit wonder, especially considering how popular it was in the early community. (Or, at least, I perceive it as popular back then…)
But I do have to question whether these games really are one-hit wonders… What I mean is, perhaps at least one of the authors listed actually has released more games, just under a different name or pseudonym. Perhaps it was their first game, and something about their online persona that was attached to that game displeased them – perhaps, despite its popularity, something about the game itself displeased them and they wanted to start fresh… Or maybe it’s for artistic purposes. After all, some works of art very much benefit from the “one-hit wonder mystique.” The aura of mystery that comes from knowing very little or nothing about an author – from not even being able to see any of their other games, of having this one piece alone speak for them – can often elevate and augment a work of art rather than detract from it.
(We can also think that they are an established author and this game was very, very different from their usual fare. As someone who has posted anon on AO3 before, lol, I understand the impulse.)
But I also have to assume some of these games really are one-hit wonders! In which case, that’s very impressive and interesting to me. What makes a first-time game designer have such a popular game and then – poof! – vanish into thin air… well, not vanish, of course. I’m sure they’re living their lives and living very wonderful lives at that. But, ah, the ephemeral nature of the internet. Sometimes people just swoop in and then eff off, it’s honestly chad. 
I will give Violet a try. I played the beginning years ago but never finished it. Dinner Bell, too, seems great!!!
Thanks again for sharing this!
