There's Key stuff which is slightly similar to KS, pretty much just slice of life and good at it: Clannad, Little Busters, Rewrite, Planetarian, Air, Kanon, with the first 2 being must-reads. Symphonic Rain is similar but not made by them, also a must-read. Ever17, Steins;Gate, Higurashi no Naku Koro ni and Umineko no Naku Koro ni are great if you like a mindfuck. Muv-Luv and Muv-Luv Alternative are the epic saga of visual novels, and Saya no Uta is sort of Lovecraftian.
