I'm not sure I have quit it for good, but I kinda fell off Star Knightress Aura because the quests I'm at have no connection to corruption, so I don't feel the gameplay reflects the sexual journey the MC is supposed to be going through at all.
I don't really like it when the porn part of the games seem completely separate from the rest. For example, one of my favorite H games is Apostle, but it's just budget Persona with porn - I think there's even a version without sex scenes, and I have no doubt the entire game will work without a hitch, which bothers me a bit.
Another thing I recently complained in another thread is life sim games. You know, games that penalize you for not eating, drinking and sleeping. I can get behind rent if there's a sexual way to pay or lower it, but overall, most daily life necessities make the gameplay loop more boring, not more fun. The Company manages to simulate the daily life of a worker (in a bizarre situation, I give you that) without making you deal with too much of the boring stuff.
