Dataminers think they've found evidence of Paper Mario: The Origami King including an experience system at one point

Paper Mario: The Origami King doesn't feature a traditional experience point system, meaning characters don't level as they fight enemies. This has rubbed some longtime fans the wrong way, as they'd like a system that's more closely related to what we saw in the original game and its follow-up. Now some evidence has popped up that indicates Nintendo may have considered that direction during development.

Dataminers have been picking the game apart, and they've found an interesting line in the game's code. In a portion of the code, there's a line that reads "battle_win_exP," which is what has everyone wondering if there was indeed a more traditional experience point system in the game at one point. Obviously we'll need a bit more information before we can say this is confirmed, but it's definitely a noteworthy find.
