I saw the trailer for the upcoming anime, and decided to give the Manga a try. I am glad I did. While the idea of being stuck in a game world isn't new, the concept of game logic dictating how you survive hasn't been explored, to my knowledge. It's not that these people are stuck in a game world, they are stuck in the game itself. And one wrong bug/glitch could leave them in a state worse than death. It's very similar to Log Horizon, but more focused on the physics and logistics of the world, instead of the politics.
This is really interesting, and the plot twist in the later chapters is very similar to a very popular games. I can't wait for more.
