I will admit that some have had an effect on me, but not in the way I think you're describing. Playing an incest games doesn't impact my interactions with other, much. I've been playing for years, and I can say that they have impacted my sex life. They have helped mold and change my interests significantly, but other than this, not much has changed.
There have been brief moments of depression in which I've found myself falling into a fantasy of some game that I had played recently, giving me dreams of the fantasy and shit. I also enjoy world building as a hobby. Just creating fantastical worlds just for the fun of it. It's kinda therapeutic to me. Adult games have impacted this hobby significantly. Several games have provided inspiration for my hobby, and honestly have completely shifted how I go about it. I used to design edgy, occult-like modern fantasy worlds, but now I focus more-so on general fantasy and often add elements of slavery, incest, and other such adult themes that I never bothered with before.
Also, aside from time sinks, nothing else has really happened.
