They have the advantage of like minded fanbase... And here opposite, literally and figuratively.
I like the way he managed to pull it out in a way to satisfact both fanbases, i always kinda had in mind a game with ntr as a consequence of your choices. Most problem with it is that: Vanilla players usually are purists, they really can't conceive the possibility of them failing. Some even act as if they didn't want to have te effort to play the game, only to see the scenes.
And NTR players are almost like a big maw. Yes, you can give them some scenes, but that doesn't mean they will be satisfied. They gonna go further and further to take every possibility they can get.
However, in my experience, i saw more vanilla players being radical about it ( because of them feeling cucked, even tho there is the possibility of turning the NTR off in game) and trying to cut off the content from the ntr players.
If the following game has zero NTR, i at least hope he tries to connect it to the "What if" game, otherwise would be a lot of opportunities being thrown away ( considering the fact that he is not making those games for free.)
