Well, I can't say I understand your POV.
I rarely play single LI games. I find the whole concept wasteful, sometimes even offensively so.
I'll try to explain. The developer used resources, both money, time, work, etc... to create a cadre of sexy women for you to choose. They created backstories, dialogues, locations, animations, the works... And then made it impossible for you to experience all but one of them.
Some even make you pursuit ALL of them, cheating on them all, and then force you to choose only one. Never mind that in the meantime you created some bond with most if not all of them, now cut all of them except one... What is this? A sadistic dungeon?
Sure, there are some decent developers where you keep a friendship (I don't even want to go into that) with the refused, as if we weren't bumping uglies a few scenes ago... all is forgotten, forgiven, no one feels cheated...
And some people have the gall to say it is more realistic...
So, I feel it is better to play them in a different way. Only one playthrough. Only one LI, chosen randomly. No contact, or just the minimum to make them go away. Played until the end. And never touch that game again.
The contrast with the Harem ones is that I replay the good Harem ones multiple times. For example, I've replayed all of Talothral games at least 3 times each. Sorcerer is the exception, it's over 5 times. Why? Because I feel happy. Because I feel respected. Because there's no "cheating".
Seeing you squander a fantastic game as this one, with very interesting and meaningful relationships, just to pick only one, for whatever reason, feels really BAD. It is your choice, don't mind me, but ...
Peace
