Seeing as we are talking about a female MC, this is defacto not NTR, even if the focus is on her cheating on their SO with many other guys, it still would not be NTR if we don't play any POV of her SO. That said, I think the focus should be equally distributed between loyal wife, cheating wife with few select people and slutty wife involving many more people. All these genre together attracts a wide audience and they are not mutually exclusive from each other like NTR/Vanilla is.
Only focusing on romance in a female MC game is extremely niche within the adult game community and will not be liked or even played by many people. The most popular games, when it comes to types of MC, is Male MC romance or Female MC slut. You will see majority games follow either one or the other with some variations/optional content because that's what most people wanna play here.
So it would be stupid to not expand on the slut content of this game, if the dev is interested in making a game people actually wanna play that is.
Regardless of your position on NTR - subsequent posts are asking for that exact same thing... I guess everyone else is wrong if we are following the Rogers Rules of Order regarding the 'proper' definition of NTR, right?
Now - onto the actual difference of opinion.
You said:
I think the focus should be equally distributed between loyal wife, cheating wife with few select people - I agree
You also said:
slutty wife involving many more people - I disagree with MANY.
The things you do not address in your desire for a slutty wife path involving many more people are:
The dev needs to change the trajectory of his story, since there is no evidence in the existing content that the female MC - Diana - is supposed to evolve into a slut who services
many more people on any path.
Each new person that the dev spends time adding to the story (by new - I mean people who were added to the story to support your desired slut path) takes time away from developing other characters and relationships in the story.
That is a given - there is only so much 'screen' time in a release for the characters present.
If the dev tries to advance the story at the current pace while maintaining the current mix of content with the existing characters, then adds in additional men/men and women (slut path), the time between releases must grow to accommodate the change to how the dev is creating/developing his story.
Since SS is still not available as an option to support the dev, I joined as a Patreon.
When I read through the comments of the last year, I saw no one pining for a slut path.
What I Did see was $ supporters who were concerned about the growth of time between releases - something that Must happen if the dev was to implement your desired slut path while maintaining the pacing of the story and all its current relationships.
Have you joined the dev's Patreon and persuaded your friends who feel the same way to do so?
Showing the dev support before telling him he needs to change his story, is one way to at least gain come credibility and show intent to back your desires with $ support after all.
Otherwise, I equate this request to that of a hobo complaining to the manager of a restaurant that the food he is taking from the kitchen is insufficient and does not meet his refined tastes, so the manager needs to change their menu to better suit the hobo and continue to give the food to the hobo for free.
What RL restaurant manager is going to take advice from this 'food critic' over that of the customers who are actually paying for their meals?
Just saying...
Cheers!!
