No Game No Life 1

The different game mechanics are so inventive and crucial to the story. I'm curious whether these rules were planned from the start or developed as the story progressed.

Some of their decisions seem pretty ruthless but also strategic. It made me wonder whether the author intended to challenge our view of morality in games and conflict.

The concept is so creative and playful, but I wonder if there was a particular influence or idea that sparked this universe's creation in the author's mind.
