Paper Mario-serien startede ud som værende et form for rollespil. Men efter lanceringen af Paper Mario: The Thousand Year Door, så har serien langsomt men sikkert bevæget sig væk fra RPG-rødderne, og forsøger nu hver gang at genopfinde den dybde tallerken med nye kampsystemer og mekanikker.
Men bliver Paper Mario nogensinde det rollespil det var engang? Det ved produceren faktisk ikke. I et interview med Eurogamer fortæller producer Kensuke Tanabe, at han og resten af holdet hos Intelligent Systems endnu ikke helt ved om hvorvidt RPG-mekanikker og systemer genintroduceres.
""When developing Paper Mario: Sticker Star, one of our goals was to move away a bit from the traditional RPG style. Nintendo has another RPG series starring Mario and we wanted to distance ourselves from it by making an adventure game with a focus on solving puzzles. Even though we've stuck to that decision so far, we haven't decided yet whether or not we will keep doing so in the future. Personally speaking, I want to keep developing Paper Mario games that are both innovative and unique. The game development philosophy I've adopted from Mr. Miyamoto is developing innovative and unique gameplay systems. I'm not opposed to the fans' opinions. However, I view my game development philosophy as separate from that. If we used the same gameplay system wanted by the fans again and again, we wouldn't be able to surprise them or deliver new gameplay experiences. We always try our best to exceed expectations in surprising ways. At the same time, there's no guarantee that we'll always succeed in doing that - so it's a real challenge."
Det er et ret interessant citat helt generelt, men naturligvis kan man pointere, at det er meget, meget lang tid siden at Nintendo har rørt Mario RPG-serien.
