NTR is about loss/betrayed love, if she isn't yours you can't lose her. But NTR arguments have been done to death, I'm not interested in reopening one here. If you really feel the need to debate this do it in a PM.The thing with LIs. Lets say we stick with your example, she will have sex through the story with multiple guys and gangbangs and every other kink and only at the end, like 80% of the content is finished, she or the Player finally has the option to add her in the harem. Does this count as a LI in a Harem game ? No.
But if you put that way that Its a NTR game first where there is a route you can win, then I agree with your statement. However people wont like it even in this path if that would happen. And I agree how things are going right now that Tiff is safe, at least for now. I mean there were at least 3x chance for him doing something but the game played it safe. Be it that it happend offscreen or not happend at all.
What was the big change in this rework by the way? I heard the "NTR" (I think he grabed her ass or something) which you couldnt avoided was the Danrell targeting Mom before. Here he said he is more into younger ones. And in this version its Tiff. I also read comments that at some point you can "Kill" Darnell and let him die, ergo removing any NTR from that point which probably Roger will replace him as a Antogonist.
Uber is very very clear about NTR, you know NTR is about to happen because it will have "(NTR Warning)" next the the option.
The rework changed the intro, that's it.. inserting new characters and fleshing out the first few days.
Darnell has always played grab ass with Tiff and always made lewd plays for Mary, it's a base element of the story he's part of a gang that drugs/enslaves women to be sold as sex slaves... he is not a nice guy.
You can't kill Darnell in this or any other version I've heard off. (There is supposed to be a Bro route, or was anyway, not sure if that has been scrapped)
