Quertus rambles about… story?

Self-insert with some extra steps, sure. There are multiple ways to get to self-insert gameplay.

But it is the case of most tabletop rpg characters (the only thing that might vary is the absurd part and the for fun part, if we allow to skip those two parts it becomes 100%).
So most tabletop rpg characters are self insert according to your vision.
