>>33248735 (OP)Play every single visual novel that comes your way on steam. That's how I spent my teenage hood (12 through 18) and I turned into a degenerate femcel who is also a hardcore lolicon.
Clannad is the best VN ice played so far, but if you aren't into romance or crying, then an all-rounder is Steins Gate (then again, it can get very scientific if that isn't your cup of tea.)
If you're into shorter games, the Nekopara series is Amanda as long as you like catgirls and don't mind paying extra for the 18+ patch.
Another good game is DDLC if you're comfortable with playing a game who's fandom is littered with retarded 13 year olds just getting into anime.
A slightly newer game is Needy streamer overload if you want some actually gameplay, though the topics are heavy is you're an easily triggered faggot.
I recommend starting with a shorter game, so something like Planetarian might be good, but it all depends on preference at the end of the day.
