Let me tell you, swinging or sharing MMF, any love interest fucking someone else that is not mc will be ntr, so if your going to add any of those 3 fetishes make sure to put a big warning because most of us dislike that and won't even touch a game with those fetishes even if they are avoidable, my 2 cents is that you make your mind soon about what kind of fetishes your game will have and what fetishes your game will never have, because if you want support that is a must for the fanbase to know.
Good luck and hope you choose wisely.
Nah. I think NTR is a pest that should be purged from the planet, and I avoid swinging and sharing routes wherever possible.
But I don't call every single thing I don't like NTR like some imbecile who uses words without knowing what they mean. Heck, even an imbecile can google things. Try it some time, maybe.
