The TL;DR of below is: It’s helpful to know which fantasy books you’re drawing from for Fantasy World. Leave these parts as they are!
Wow, I haven’t read most of those books! This is a great list. Sounds like I’ve got a lot of fantasy books to read. :)
The immediate but largely irrelevant answer to your question is… plenty of fantasy novels feature sex.
I don’t think this is irrelevant.
Fantasy World fosters a narrativist agenda, rather than a simulationist one.
I know! Like you’ve mentioned elsewhere, narrativist agendas borrow tropes from stories and fiction to build mechanics that emulate certain kinds of stories.
This list is super helpful to me because it made me realize that I thought I knew what kind of fantasy stories you were drawing from, but it turns out I was wrong!
For the stories and tropes you’re emulating here, yes, “fornicating” and “lust” make plenty of sense to have in your game! I had just misunderstood the kind of fantasy you’re emulating here, which I would call “adult fantasy.” Most of the fantasy I’ve read and seen has been, like, “young adult/children’s fantasy,” like Lord of the Rings, Redwall, Howl’s Moving Castle, Ella Enchanted, and lots of others I’ve forgotten the names of.
