Any serious/hardcore visual novels you recommend that are on steam?

[Empanda]

Just looking for more visual novels to add to my collection THAT ARENT FANSERVICE-y. I already got corona blossom triology so im good on fanservice. Just looking for some good visual novels that will give me a good story. Only visual novel i got on steam that I havent played is Memoreis Dogma CODE:1. Looking for others to buy that i havent played. Realy interested in horror-ish, sci-fi, mystery, and drama types visual novel. Really don't like romance visual novels unless its otome's...like hokouoki. Which is funny cause my anime taste mostly on romance but hate the other stuff....weird...anyways here are the list of visual novels i know are on steam but i played or already looked at:


Steins;gate (love it on vita, might buy it on PC again for that HD and to get the perfect ending that i missed. Havent watch the anime doh)

danganronpa 1+2 (might get 3 on pc instead of vita, maybe. might ruin my collection doh)

zero escape triology (eh I tried getting into it but i can't, my friend keeps pushing me so maybe one day)

psycho pass mandatory (alreayd got the collectors on vita)

blazeblue games (already have them on consoles, just bought the pc for support)



But yeah recommend anything you guys recommend as long its not a dating sim (already crossed out 90% of the VN's on steam but there you go)
