I got this response in a game thread (AlwaysFan): "No, NTS just means you're sharing her. Treating her decently isn't a requirement for that kink". The point being that in that game, you can share your girl if you don't really care about her, and you'll have to force it on her because she doesn't want to be with any other man than you (the MC).
My question to this thread: I thought, especially from reading here, that NTS had a more "positive" vibe, involving consensual relationships with others, swinging, open relationships, the lot. The claim that "treating her decently isn't a requirement for that kink" is kinda news to me, and a bit disappointing, really. Makes me think that a percentage of the games I was thinking about playing will disappointingly feature an uber-dominant MC that alone makes all the decisions about their LI's ability to pursue other relationships. In other words, puppet-master games. Not to mention games where you're expecting an interesting sharing path, but instead you get a path where you can whore your LI out... Very realistic, indeed.
I'm not a psychologist, but can't help thinking that open relationships, on one hand, and forcing your partner to accept having sex with someone else because you want it and you assert your dominance, on the other, are completely different kinks...
