Well, I’m still incredibly new to untranslated VNs, so I don’t know how much help my thoughts will be, but I guess I could do a post on what I’ve read so far.
Euphoria: it gets a bad rap because of its extreme content, but it’s actually got a pretty interesting story. I’d recommend checking it out when it comes out in English if you think you can stomach it. Worst case, skip the h scenes.
Fraternite: thought it would be like euphoria. It wasn’t. It was terrifying. Moving on.
Mashiro Summer: a little-known gem I stumbled upon on vndb, and ended up giving a shot after hearing the opening by KOTOKO. It wasn’t perfect, as it had some painfully boring slice of life during the routes (as well as one awful route that took me a month to finish because nothing happened), but the true route- as well as some other heroine routes- had some near Key-level drama and unique circumstances. Would definitely recommend this one here of all places, as I know for a fact most of us like that sort of thing.
Those are the only ones I’ve completed so far. Right now I’m reading Midori no Umi. I’ve heard it gets pretty creepy later on, and there are hints that not everything is as nice as it seems, but so far the common route is a pretty calming read.
