Well, there is Ever17, which is still one of the best things I've ever read. It's quite popular among the western VN community as well (and with good reason). It's even ero-free!
It's also plagued by an absurd amount of spelling mistakes, as it was literally rushed out of the door by the company that translated it. Suffice it to say, they didn't last long.
Such a shame. I would really like to legally get my hands on the other Infinity series VNs. I read some of the fantranslated ones, and they're all absurdly good. It will probably never happen, though... unless I do it myself, but that'll take a while yet. If it's even possible to license the games still, as KID went under years ago
I'm just glad I managed to secure a copy of Ever17 in time.
Speaking of Ever17, 999: nine hours, nine people, nine doors was written by the same person. Pretty sure that game did reasonably well, too. It's a DS game, though. So that might be partially why. There is also Hotel Dusk and its sequel, but again, DS games.
