Trivia / Paper Mario

• Exiled from Continuity: Due to Nintendo’s mandates, original characters of at least mainline species (such as most of Mario’s partners and Kammy Koopa) from games released prior to Sticker Star are no longer allowed to make appearances in the Paper Mario series itself. This restriction does not appear to be retroactive, as the September 2023 Nintendo Direct trailer for Paper Mario: The Thousand-Year Door’s remake showed a number of theoretically affected characters keeping their designs, with newly created poses and back viewing sprites to boot.
• What Could Have Been: The series was originally envisioned as a sequel to Super Mario RPG. Nintendo had approached Square, now Square Enix, to develop the first game, but they were too busy with Final Fantasy VII.
