 "I finally realized: I'm not sick, I was never sick. I just live in a sick society, where someone's individual worth is measured only by the raw productive output they can spit out before getting chewed up by the gears"
+
+The Player Should'nt be special (Chosen one) but should become by is action. either become a hero or becoming a demon king
+
+The Time Should Flow to make the world feel alive when the player isn't in a place (make things happen)
+
+A lot of things should be hidden to the player, the player shouldn't know everything.
