I have been reading a few VNs since the last years but I have not found any recommendation about a Visual Novel about vampires.
If you know a good VN about vampires please recommend me one (I like stories about vampires)
There's "Vampire: the masquerade - Shadows of New York" and "Vampire: the Masquerade - Coteries of New York". They both have just around 3/5 stars on gog, so I dont know if they're actually good. I enjoyed playing them a few years back tho
It's probably better to play the standard Vampire: The Masquerade, although it is not a VN it is a story-driven RPG, and it's commonly regarded as a masterpiece in its genre.
