In an interview with GameXplain, Risa Tabata revealed why they weren’t making Paper Mario games as RPG’s anymore. According to her, this was due to the success of the Mario and Luigi series. She thought that an RPG Paper Mario game would be too similar to the Mario and Luigi games, so they decided to throw away the RPG elements and focus more on the humor and puzzle solving aspects of the first two games. Although she said they would not be focusing on any more RPG Paper Mario games in the near future, she did not rule out the possibility of a Thousand Year Door remake. Fingers crossed!
