I remember playing a very basic text based game that was about kidnapping local shotas and lolis and keeping them in your basement but I can't for the life of me remember what it was called
I LOVE the scene in Nudist School where the MC has a boner (which is not allowed) and 3 of the girls help him get off quickly so their teacher doesn't notice.
I always prefer when a VN gets straight to the game/plot/whatever instead of having a huge intro full of dialogue choices that won't impact the story later.
TBH I also LOVE when a game just gives me the cheats right at the beginning. Sometimes I wanna play the game, sometimes I just wanna get right to the part where I'm touching myself.
I hate when games have "sex scenes" with a character, and then it's just kind of skipped. I get that usually it means the dev didn't have the time/whatever to add in scenes. But at least add like, a picture!
