Your thinking is logical, but theirs is not. Fundamentally, they want a cuckold story where the male MC suffers enormously from his partner's sex life with others, even tries to take his own life(according to his game reference ). They want a twisted game to mix cheating and cuckolding altogether. However, a man getting excited and enjoying the pleasure of sharing his partner is the prerequisite for any cuckold game, logically. So they have to confuse others with a vast "dissertation" to justify an apparent antinomy --- a cuck man should share his wife painfully in the whole process. So, no matter what you say, they would drag many other variants into the discussion; it's pointless. I don't understand how frustrated a person can be when they squander valuable time like this.
Incorrect, it was already shown to you that cuckolding is not Netorare, that is approving of the cheating and partaking in it. Netorare is the story of the MC unwillingly being cheated on, the FMC having an affair unbeknownst to the MC and the process of him suspecting and slowly finding out that she has betrayed him. A natural Netorare progression is a resolution when this is understood which is why many NTR games of actual Netorare focus provide a complete cycle to the progression from happy relationship to suspecting to knowing to resolution of some kind.
The resolution can be anything be it confrontation and washing his hands of it, revenge in various forms being immediate or planned retaliation, even the dark suicide ending is a completion of cycle, etc... The point is that it is a cycle.
Cuckolding is more Netorase, where the MC partakes in the approved cheating in some fashion (watching, sharing, etc...). This is not Netorare.
What you prefer is Netori, the perspective of the cheater (which is why you say you enjoy the FMC view of the cheating).
What you confuse here is that you want a Netori game, but wish to play it from the Netorare MC perspective. I can only guess this is because you take pleasure from being the cheater and then also watching the misery and pain of the MC through his own eyes rather than from the cheater perspective, otherwise you would advocate for a more traditional Netori style (MC is the cheater).
You think it is somehow sick that Netorare MC would want revenge, but as we already know, it is because you seek Netori and obviously a Netori seeker isn't going to see the value in themselves being punished for cheating/betrayal.
The problem here is you don't understand the various types of stories there are because like most of these Western versions, they simplify Netorare into one package and then put into a netori kink package, which it really isn't specifically in that form (as was shown to you previously). There is nothing sexual for many who enjoy the Netorare story progression, it is much like watching a hero story that goes through a terrible loss, deals with tragedy and then the story progresses to some resolution of some value be it good or bad. It is an emotional story of ups and downs.
You could remove all of the sex scenes entirely in a Netorare game and it would still achieve the same goal of its story progression (Which is why some Netorare games will even have very little actual sex scenes).
The problem here is that you refuse to accept this and misclassify things because the idea repulses your idea of a "sexy" game, because as I said... you look for the sex kink in the game through Netori.
It is not a "sadistic" thing to want to see justice to those who betray, it is a natural concept of one who is cheated on and in RL it has resulted in serious consequences for cheaters in numerous ways. This is a component of that emotional roller coaster which finds some sort of resolution, even if it is the MC being able to speak their peace to the FMCs betrayal and walk away with some dignity. Even in a revenge line, the pleasure isn't in the actions themselves, but the consequence being given to the ones who betrayed, that is the pleasure in the resolution of the story, that justice was done to those who would act and betray in such a manner.
That however would again... get in the way of your desire to be the "hero" of the story by watching in "sexy" fervor how the MC is cucked constantly and demoralized while the FMC take great pleasure in their misery and suffering. Now that... I would call that pretty darn sadistic.
The reality is, a very small portion of the world will accept being the "cuck", but some can appreciate a story of love betrayal, which I am sure you can find tons of movies/books that are not porn which attend to that concept in some way.
But hey, you are here just for the sexy kink, and that is fine, but don't act like you have a clue about what you are talking about, because you don't.
