Finish half of the game, before even putting it out there, at least you will know it will be a success or not based on feedback. Then you can immediately abandon it or finish it. I hate it when games have hundreds of v0.xx releases.
Basically, you think you like that kink/fetish before playing the game that heavily about that kink/fetish. After playing you realize you are actually not that into it.
Or which game made you confirm that you really don't like a kink/fetish you already didn't like that much.
I enjoy any game if its good, but if walkthrough is forced i skip it, I don't use it even if its available, I learn by playing it if there is anything to learn.
