Hmmm... if it helps, growing up remembering those books does help with marketing CYOA games. They're basically electronic forms of the books, at least.
Yeah, there are pros and cons when it comes to marketing naughtier games. They're definitely harder to talk about on regular platforms, so I don't really promote there. What helps is that my audience is niche though, and they don't seem to favour Twitch very much. I'm personally not on Steam, Gamejolt or Newgrounds either - not a lot of the stuff are my cup of tea, so I haven't bothered with those places, and a number of the ones I know don't either. They just swarm away like flies once there's no more naughty to be had and... go elsewhere where there is. So that's where I go too.
The only games I've had difficulty marketing are ironically SFW games.
