Some of the reviews wish it were longer since it felt like a greatest hits piece to them. I suppose that makes sense since it covers such a large amount of time.I’m definitely not an expert on fan-translations and mostly play on consoles/handhelds, so I hope someone else in this thread can chime in.
The first three Infinity series games (Never7, Ever17 and Remember11) got good English fan-translations. The fourth game in the series (12Riven) is the last one where Uchikoshi was involved. The fan-translation was never finished, but 12Riven is generally considered worse than the previous three games in the series so you’re not missing out on too much. When you say PC VNs, the Eve series, Desire, Doukoku and similar games come to mind. I think some of them are available in English either officially or via fan-translation. Some of those games got remakes on Vita but I’m not sure what the state of Vita fan-translations is right now. I think a good place to check for fan translations are the fuwanovel forums.
From a collector’s perspective, the language barrier of VNs has helped to keep prices down compared to other retro games. There’s a few really expensive adventure games / VNs (e.g. Dead of the Brain on PC Engine), but in my experience retro VNs can sometimes be hard to find but mostly aren't super expensive. There’s almost always one or two weird VNs on consoles that you typically wouldn’t associate with the genre: Yakouchuu on GBA, Yakouchuu 2 on N64(!), Terrors 1 & 2 on Wonderswan, Higanbana GBA and PS2 (the follow-up to Otogirisou by the same author), etc. Not saying those games are good or long-lost classics, but they make for cool collectibles if you’re a VN fan and on the hunt in Den Den Town. And most of the classics are available on multiple platforms and you can find them used for under $10 (Infinity series, Machi, Kamaitachi series, etc.)
One more tip: There’s a lot of really good books about all kinds of video game subjects with information that is often hard or impossible to find on the internet, at least in English. Keep en eye out for them while you’re there, even with the language barrier you might still find out about some interesting VNs. I can recommend this one about VNs/Adventure games from 1980-2000.
I've been looking into books, and for ADV at least, it dries up past 2000. Suppose that makes sense since that was right before the genre's decline in popularity. Mainly searching for encyclopedias/bibles/catalogs.
