I agree with this, it's not that bad, but if there is one thing I would criticize it would be this, I also wouldn't mind a bit less porn logic sometimes. What makes AVNs (good ones) enjoyable is well-written characters and interactions between them, believable emotions. Porn aspect is important to spice the game up but not to the point where it dumbs the characters down too much. Otherwise you could just watch actual porn, as it has way better quality scenes.Yes, and that's one of the worst things in the game. This magical porn universe where no one is ever jealous or insecure. It's an even stupider trope than the 'everyone want the MC' trope.
This is why I have zero interest in any kind of harem paths or that kind of games in general, the whole idea is just absurd as you said, from the fact that it eliminates normal human emotions like jealousy to the fact that all female characters are supposed to be acting as if the MC is the only man in the world. It's a very far-fetched fantasy and definitely not my thing.
As I said, this game is not too bad in that regard, but it does feel as if certain characters have a switch that turns porn mode on and off. A prime example of that is Sage at the end of Episode 9. This is an unpopular opinion here and I understand that people want to see those scenes, but this is what I think of it. A guy just recently told her that he wants to try an intimate relationship with her, and the first thing she suggests to her new boyfriend is to invite other people to their bed and set up orgies. Yeah...let's pretend that sane people do that all the time. And it's a shame because I like her character a lot, but this moment does dumb her down to that porn logic level. It's possible that even DPC realized he's overdone it because in Episode 10 her behaviour is way more natural.
Surprisingly, the character that shows the most of this kind of emotions in recent episodes is Quinn. She won't admit that, but it's clear that if you are on her path (or were before and then commited to someone) she is very jealous, and the way she shows it is in line with her character. At the Halloween party she doesn't want him to fuck others, so she presents it as a challenge to "keep it in his pants" if he wants to get her, but she can't admit the actual reason as that would be showing a weakness. Josy in case you were a part of the throuple and then left them also behaves very natural and human, it might not be nice to see and many didn't like it, but there is nothing wrong with it.
