Oh, I see. I didn’t mean to imply that Western or Eastern tastes are better or worse, not to mention the cultures or ethics. But since you brought it up — are there more incest games because, culturally, Western sons are more sexually attracted toward their mothers, and the mothers are easily tempted?
Eastern females are still fairly suppressed by local society and raised to be submissive to their partners which make it REALLY unlikely for them to cheat since they are simply gonna be crushed by fear and guilt indocrinated in them since childhood.
Western females on the other hand have more rights and freedoms and thus can be, eh, confident (?) enough to cheat on their partners. So in a way yes western people have easier time getting tempted cause there are much less restrictions regarding one's sexuality in west.
So basically for eastern dude NTR is truly more of fantasy or something he can be sure not happen so he'll be more chill about various games/comics/novels with ntr theme.
For western dude though NTR is much closer to reality so he'll be more wary or hateful towards works with this theme.
Well, this my take on this at least.
Now about the game. Is there gonna be only one "bull" or several dudes that can cuck mc?
