idk in lots of games dev trying to avoid ntr tag cause using same logic as u sayed now....she is not his LIs yet so she can fucking anybody....
In this case she is a LI. So is NTR. If that happen i am not interessed in the game. Its pretty easy.
I can understand world build, i can understand put other men, to make a good plot.
Till the men do not touch the girls/women, is called world building. Just to make the story a bit harder.
I don't like it, but it can be accepted. As long as none of the potential love interests do anything with other men.
Ofc if the developer wanna make a to much slutty mother, no thank you.
As i say i can accept a sexually frustrated woman. An idiot husband who doesn't think about her, so much pressure, so much dissatisfaction. There may be that this happens. But it has to stay there like a phone call. At the time, the developer decides that they meet and have sex and the MC can't stop it. For me it's simple, I delete the topic and move on to another game. Simple. I haven't even played it anyway, I'm just observing.
I'll play if it suits me. Otherwise I'll go away. Here we can only advise, not oblige. It's up to the developer to figure out who he wants to follow his game. What target is it aiming for. If he tries to make money. My advice is:
The game need to be:
Harem/incest/netori stop.
If he want to make lass money, put everyting he want and in like within 3/4 months this game died and he simply wasted time to do something else.
