Paper Mario: The Origami King once game minimizes role-playing elements, and once again, that doesn't serve the series very well.
Paper Mario: The Origami King is not the return to the traditional roots of the series I was hoping for. Like other recent entries in the series, it de-emphasizes character-progression elements to provide a simplified role-playing-game experience. And yes, that means Mario doesn’t earn experience points for battles and doesn’t level up as a result of those fights.
Why does Nintendo refuse to Make Paper Mario Great Again?
