In a way it is. We are all living in a guarded community where our language and its derivatives - stories, identity, science are the barbed wire protected walls.

The three player have each made their own protagonist who deals with things in their own way. One is mad, cruel and ambitious, one is conformist and doesn't question things, and the last hates the system and avoids magic and Gods as best he can while reluctantly taking care of people they meet. So these three roles have each found a sort of way through all the cruelty. They are trying to figure out what is going on and to analyse all the forces that are manipulating them while they also are part of the system. In reality it is really just like the rest of us :)

and gives credence to the claim some make that we are all living in a vast simulation.

The brain in a vat theory :)
