i know that's like 80% of the games
I know I sound like a broken record correcting people on this, but Hentai games comprise like 4% of the PC-FX library.
after going through the pc-fx database and game overviews, i pleasantly realized you are right! it's good news because even though the library is small, there seems to be an interesting selection of games. of course some of the ones that interest me are the most are high-priced .
Yeah, the library is less than 100 games total, but is rich in RPGs and the quality-to-crap ratio is excellent. There are few true "clunkers" that I've encountered so far in my FX experience. The downfall, like you mentioned, is many of the best games are way overpriced. Zenki: Vajura Fight, for example, is a fantastic game but definitely shouldn't cost more than $50 though it commonly fetches hundreds of dollars.
