I accidentally came across this while trying to get Never7 to work, seemed worth joining.
I have some experience with VNs though mostly mainstream ones, I guess I might as well actually list them.
Fate/Stay Night, Fate/Hollow Ataraxia, Tsukihime, Kagestsu Tohya, Grisaia, Chaos;Head, Umineko, Katawa Shoujo, and Muv luv.
Other than that I guess there are some game VNs like 999 and danganronpa if that counts, but I'd say that's about it, feel free to suggest anything.
