You probably don't realize how you touched the key issue here
You see thats exactly what doesn't happen with Icstor. What is happening with you. "The story going on my mind". Now this, my fellow Zoner, does NOT happen with Icstor. I'm fairly confident that this is the actual genuine core reason behind all the failings.
He doesn't think in story. He doesn't really want to tell a story, he gains his motivation to deliver the lewds so when that starts to happen well.. he satisfied his desire. The main source of drive is gone. Its game over.
This is the key difference between someone who is trying to tell a story, with lewds, and one who only puts in the story to make the lewds more spicy. Like sexual roleplay. The goal there is still sex. Icstor simply didn't come to realize (that, or he simply keeps this fact to himself really
) , for whatever reason, that he will never be able to just "continue" with a story because he never intended to tell a complete story the first place. He is just doing sexual roleplay.
Imagine having a girlfriend who dresses as a nun for sex. Then you would nag her to tell the life story of the nun she is dressed into. What happens with her afterwards and so on and so forth. Same thing here. Icstor simply loses motivation to carry on after the act. It was all about the act for him. For some of his players its just as much about the story before and after the act.
Simply put: There is an insurmountable chasm between his reasons of making a game and what a lot of people expect from him. And this is beside the money aspect.
