I think most people don't mind that there is NTR stuff as long as it can be avoided. If you're guaranteed to lose, that's when I think most people get really turned off by it. You should be able to defeat your opponents.The newest update is the end of the boat storyline but i do get what your saying as im not a big fan of ntr in general and even less of mr silvers i cannot say i would be disappointed. However i think most players are of the opinion that they want to keep Christine to themselves. It really depends on the dev and if he listens to his fans and supporters im happy the way the game is with ntr optional that way it makes both sides happy
My only complaint as long as that is true is when I compare the progress that's possible in both paths and find out that it's not possible for the MC to get as far as his opponents could on the NTR path. That was actually what prompted me to make my mod. The hot tub scene bugged me when I saw how far Robert could get compared with how far the MC could get even if played without any mistakes. On the flip side, there are some scenes for the MC that don't have any equivalent at all on the NTR side (like the Spa) so I guess maybe it was decided that was the trade off.
Having a worthy adversary makes for a better game IMO, even if you don't like NTR (and I generally don't). Robert and Silver are legitimate threats in this game and that adds to the tension. And while you can do poorly on the vanilla path if you make mistakes, you generally can't lose to Silver or Robert unless you do it on purpose (although there are a few scenes that kind of straddle the line on that point). I think the game would be less satisfying without them even on the vanilla path.
This game seems to be set up to have basically 4 primary paths that you can focus on. Either Vanilla Horny, Vanilla Friend, NTR Robert, or NTR Silver. Whatever your proference, if there's going to be 4 viable but separate paths, IMO they should all have scenes that are at least roughly comparable from the standpoint of how well rewarded you feel you did playing 1 path without any mistakes vs playing any of the other paths without any mistakes. I think for the most part this game does a pretty good job with that, although Silver fans probably have a legit complaint on that front when compared to Robert.
