When a dev tries to please everyone and starts adding content to the game that they had no desire to make and makes no sense to be added eg adding netorare to a Harem game cause some people requested/ paid for said content or adding optional Netorare or Harem options to a game that was originally supposed to be a ntr game
Tags that I really don't like are real porn and text based games not to keen on netorare side of ntr games either but will play odd couple if they are well made
When I have to start a new save because the update was too much for saves to carry over.
I get it, its just a little annoying to have to go through several in game days holding Ctrl to play the new bit.
As for tags, Real Porn, Censored are hard no filters. Otherwise, if it's NTR or futa centered, it's a hard no. I can do if avoidable or just a brief interlude.
For playing, if many reviews or comments have the word "grind" in them, it's a skip. (Or gallery cheat if I otherwise like the action)
I quickly lose interest when there is no erotic build-up and the girl sucks dick after two minutes of the game. This is an absolute game stopper for me.
Overpromising and underdelivering, constant delays among many other things. Some games kick off really well at the beginning and then end up hitting a wall for so many reasons, be it poor decision making, trying to appease platforms and/or people that are requesting content that wasn't intended for the game. Seen that quite a few times
