Yanderes can be cute in a creepy sort of way.
I've never actually played a dating sim... back in the day you had to download the Japanese version and then either guess at which button to push or have an English guide handy, and it all seemed way too complicated to me. Plus the only ones I'd be interested in are probably BL ones, and let's be honest, it's basically just pressing buttons to get to the SUPER X-RATED scene at the end which is totally not my cup of tea 
Like I remember Gakuen Heaven as one of the first anime I ever watched, and I heard it was based on a game, so I looked it up (of course this was before Google) and wow, it was so shocking... the poor main boy was basically a bicycle for different sex positions with the other boys
I noped outta there real quick haha
Yeah, I mean there's some that I really want to try, but the effort to actually buy the game, (which for the really good ones can be super expensive), and then find the English translation patch is really...just ugh. Dramatical Murder, (I think it's called), is the one I'm most interested in at the moment, (and I am not usually a fan of BL at all). The story just seems so interesting and apparently it has a lot of the tropes that I love, (like the insane bad endings). But a lot more visual novels and dating sims are coming to Steam, which is great and I am buying more or less all of them
. A lot of them, even when they're bad, they're just so bizarrely, enjoyably bad, like watching the Room and I LOVE it. And if I were you, I'd keep my eyes on Steam, because I know there's a lot of upcoming stuff which will be relevant to your interests. (And usually the Steam version edits out the sex scenes)
I don't think my Quizzy would, but mainly cos she's an elf and Lavellan, (at least according my interpretation), refers more to her clan name than her actual surname. And I don't think a Trevelyan would either considering she's noble and Cullen isn't. Not that I think they would change anyway.
