Repetition is educational. We learn when we have something drilled into us until it becomes reflex. I know how to step when I block low with my forearm. I don't necessarily remember the pattern, but my body moves the way I was taught years ago. Formula is comforting, and slight variations upon a theme is essentially the structure chart for serialized fiction. Repetition is one of the most important concepts to both the natural world and entertainment. It's a key part of poetry, the scientific process, math, psychology, fiction, and, well, everything really.
So if repetition is truth, is Bravely Default the truest game ever made?
