I liked the story before Stein's Gate. It was fun. But Stein's Gate was very boring. And then we were hit over the head with a "system update", all just to create a conflict out of nothing. After all, the author felt that the main character gets everything too easily, so he should suffer a little. I hate such plot moves. Initially, the story positioned itself as Marty Sue, so leave it that way, that's what I came for. I came to read a story where the main character gets everything, where the main character is the strongest, coolest and most beautiful, conquers the worlds of anime and everything else, not this.
I liked the story, but somewhere after chapter 110, it was as if another story had begun. As I understand it, the author edited his work, and the editing only reached chapter 110. Therefore, I see no point in reading further.
