It's obvious that to create a 10/10, or even a 9/10 game, a “highly-rated story” is a must-have. However, first, I can also argue against this point, that “gameplay” holds equivalent value. Second, I'm not currently talking about creating a “masterpiece”, but just a “good”, or at most, a “great” NTR game, and I'm trying to speak objectively here, because subjectively, Nebel is already a masterpiece in my heart.
Regarding this, I will neither agree nor disagree with your opinion. Simply because it's leaning more towards a subjective perspective. Just like how you don't like Nebel as much as NTRPG2, while it's the opposite for me.
Nebel certainly doesn't have a “highly-rated story”, but hey, I never said it didn't have a good story. Similar to RinaTest, in terms of overall story, it's only at a 6/10, but it did its job well: perfectly complementing the “gameplay”, rationalizing decisions, creating conditions to showcase the game mechanics, and giving those mechanics the necessary weight, thereby elevating itself significantly. Because as you said: “Even just a small interaction between characters and how that develops is a story”, and I'm pretty sure that the process of observing the heroine in Nebel also counts.
That's exactly what I meant when I said, “A good NTR game doesn”t necessarily need a highly-rated story”. It doesn't need a highly-rated story; just a good story is enough. Other than binary stuff like "does the game even run".
In the debate on this topic, I once said, “In my opinion, a good NTR game is one that expresses the NTR element in the best possible way”. Therefore, even though I've been arguing (?) with you this whole time, my stance could just as easily be modified to: “A good NTR game doesn't necessarily need a highly-rated gameplay”. Every game has a different approach, and all those approaches are equally good if they are “expressed” in the best possible way. Nothing is perfect, so no single approach is the “best”.
So, in summary, the only thing I want you to take away from this is to observe things more objectively. I'm not saying all the games you find bad are actually good and just coincidentally not for you. But at least I hope that you will consider that possibility a bit more carefully.
