I do have a few turn off, but Im mostly fine with everything as long as is not forced
Turn off:
-Male domination. I don't like seeing dudes treating badly a girl, even if they are into it. That said if is in the context of the plot Im fine with games with villains who do crappy stuff
-Scat. Obviously
-Pregnancy. Im just not into that.
-Watersports. Again, not my cup of tea.
And that's pretty much it. Now there are stuff I actively look forward and Im willing to ignore a few flaws in games that contain
+Femdom.
+Futa/trans.
+Wholesome slow burn romance.
+Something very unique, maybe having a few non conventionally attractive LIs like
Light of my life or having an unusual setting like
Exiles will help a lot into making me play your game.
But as I said, variety is the spice of life, having options is always good, and people with niche fetishes are usually the biggest fans and the most willing to support games that cater to their fetishes so don't shy away from getting kinky
