somewhat honest question: does anyone play TiTS for its somewhat decent writing choices as just opposed to just a sex game?
Honestly no, for me it mostly stems from how unlike the original CoC(I could actually play this one in the way you're describing) there's not a real thematic justification for so many of the characters being as openly sexualized as they are while also clashing with the fact that some of them have hang ups about things that don't seem to make any sense in relation to other characters. For example Kaede has a scene on Canadia where she'll be against exposing herself in public implying it would be indecent exposure which isn't helped by the fact that Kally is just running her place while serving people with her dick hanging out. And there's a lot of little stuff like this that just makes it kinda hard to actually put myself in a mindset to actually take the story seriously.
I liked CoC 2 when it first came out as it was actually better at this type of stuff at first but even that started to have similar issues. For example stuff like the Kitsune being portrayed as being lecherous and hedonistic only for one of them to be up-tight and rigidly hierarchical with one of them saying their society is that way to keep their "hunger" in check which conflicts with their original portrayal also the fact that Miko just acts that way anyway.(Also the fact that even though most of the Kitsune stuff is all written by one person the player character doesn't even act consistent with them, like not caring in the slightest about the Kitsune being racist in one scene only to have you be able to choose to punch one in the face for being racist towards you in another).
So it really feels like an issue in general that's not just limited to TiTS of them not setting some sort of base for how characters and content should work with the world building they're setting up and so you get a lot of little bits of this incongruous stuff popping up. Which sucks because there are parts of both games that have genuinely good writing or at the very least have a decent hook to them that is kinda hurt by it being included alongside stuff that makes it harder for me to get immersed in the story itself.
