There are worse things (from my point of view) than the NTR. For example: rape, graphic violence such as the amputation of body parts, cruel and merciless abuse, sexual harassment... All this barbarity has a name: Red Room. I deleted this game from my hard drive and from my mind. NTR can generate some concern, which can be aggravated by the experiences that a user may have had in their real life, but I repeat what I said at the beginning of the text: there are much worse things...
I'm not passionate about NTR, but when I find a well-made game with this theme I don't say no to it. A clear example of this; My husband's boss.
Of course those are much worse things, you're talking about barbaric stuff, and I'd despise any scene depicting that on any game that I play. Still, the fact that there are worse things on paper than NTR, doesn't make me enjoy it. I know for a fact that I'll never be able to like an NTR-focused game.
If I could dissociate from the story and experience it from a viewer's perspective, as if I was watching a movie or a TV show, then I could see myself indulging in said content. But there hasn't been a single AVN in which I haven't immersed myself, even if it's just a little bit, and that makes it impossible for me to like any NTR story.
Like I said previously, I don't judge anyone who enjoys NTR content and much less the quality of games with it, I know that some of those titles (like the one you mentioned) are highly-rated for a reason. Still, this is just my personal preference, as there are certain things that I can't stomach, and this is one of them.
