Hey all. So recently I've managed to introduce my brother to the wonderful world of VNs and in fact he's already read quite a few (he even outpaced me in the vns I'm reading) He's planning to read G-Senjou no Maou next so I'm wondering what other vns I could recommend for him to read after that. Here are his criteria:
Preferred Genres: Mystery, Adventure, Suspense, Sci-fi (Other genres such as romance are ok for him, but it's not a priority)
VNs he's already read: Steins;Gate, Ever17, Never17, Remember11, 999, Ace Attorney Series, Dangan Ronpa, Katawa Shoujo
VNs he plans to read but aren't his priority right now: Fate Stay Night, Clannad (for that matter, anything by Key), Higurashi & Umineko
18+ VNs are okay. He prefers the VN to be of average length (around 10-30 hours?) . Gore is okay, as long as it's not graphic. He wants the art to be at least decent to look at (he thinks the girls in Key look like lolis, so he doesn't want to read anything by them yet). He also prefers the VN to have choices (hence why the When They Cry series are of low priority). English-translated, of course.
