Paper Mario: The Thousand-Year Door is a role-playing video game developed by Intelligent Systems and published by Nintendo for the Nintendo GameCube video game console in 2004. It is the fourth game in the Mario RPG series, second in the Paper Mario series. It is the successor of Paper Mario and uses the same gameplay and visual style but with improved visuals, and is also the predecessor of the Wii game; Super Paper Mario. It frequently plays on the "paper" aspect of the universe and its characters, in a sort of fourth-wall breach.
