Honestly, it seems like a shit marketing strategy if you think about it. The motif of cuckoldry/stealing/competition in the story is shit taste for (utterly superior, virtuous, and morally right) ntr-haters. but the actual lack of cuck scenes does no justice to the cucks. One has to wonder why they decided to do things in this way.
not to mention the very hit-or-miss art style.
I disagree on that it's a bad marketting strategy. it gives us a tease for what's to come and keeps us on standby, and there's plenty of ntr fans, and some appreciate the game even if there's no ntr route implemented yet, of course people went away due to the tease, but nothing that puts any dent on uber's wallet.
and you wanna claim superiority, being virtuous, morally right when you support a game with rape, blackmail, stalking, cheating? jesus, we're all degenerates here. Atleast ntr fans concentually approve of being ntred, while you guys just accept cheating outright in these games. non is superior, just different tastes man. and everything's fictional, so really it doesn't quite matter.
that "hit or miss" art style was a big reason why the game succeeded btw, your taste in it's art style is not fact, it's in fact very unpopular.
