Paper Mario: The Thousand-Year Door (Nintendo Switch)

Paper Mario: The Thousand-Year Door is an upcoming game for Nintendo Switch. It is a remake of the 2004 Nintendo GameCube game of the same name. It was announced in the September 2023 Nintendo Direct, and it is scheduled to be released in 2024. The title will feature visually enhanced and updated graphics. However, the characters still use their designs from the original release, rather than the updated designs used in the later Paper Mario games starting with Paper Mario: Sticker Star.

Despite the various voice actor changes since the game’s release, the voice clips from the original appear to be reused.

Gameplay changes

 * During battles, there is an option on the bottom right corner of the screen known as "Tattle Check".

Text changes and localization

 * The game has now been translated to Chinese (Simplified and Traditional), Dutch, and Korean, three languages that the original was not available in.
 * Characters are given unique talking sounds during dialogue, similar to the Mario & Luigi series, Paper Mario: Color Splash, and Paper Mario: The Origami King. Luigi and Princess Peach, for example, have talking sounds similar to their voices, while Koops has talking sound identical to modern Koopa Troopa vocal effects.
 * TEC-XX now has a red eye in all regions rather than only in Japan.
 * The game's logo in international regions has been redesigned to resemble the Japanese logo of the original game more. Conversely, the Japanese logo is now primarily written in English, matching the design conventions of the series's Japanese logos from Super Paper Mario onward.
 * There is a "Superguard" text pop-up that appears when the player successfully performs a Superguard. The original game displayed a “GREAT!” text instead.
 * Text is now vertically centered within text boxes; in the original game, text was aligned to the top of the box. Also, some text has been reformatted due to the higher screen resolution allowing for more text per line.
 * Some English character dialogue has been altered slightly from the original game. For example, when Mario enters the town square of Rogueport for the first time, Goombella states that she is a "Student at the University of Goom", while she instead states that she is a "Junior at the University of Goom" in the remake. Another example involves Bowser using the insult "Lunkhead" in place of the word "Airhead" during the Bowser interlude after completing Chapter 1.
 * In the Italian version, the name of the University of Goom is changed to accommodate the renaming that was done in Paper Mario: Sticker Star.

Graphical changes

 * The entire game has a higher-resolution, more crafted appearance similar to Paper Mario: The Origami King. For example, the characters now have a softer, felt-like texture, while the pigs have visible seams on them. To go alongside these changes, dynamic lighting is now present extensively in many areas.
 * The game runs at 30 frames per second, which is half of the 60 frames per second that the original game runs at.
 * Characters are generally more expressive, such as during the kitchen mystery on the Excess Express.
 * The Mario Bros.' House has a group picture of the partners from Paper Mario as a call-forward to Super Paper Mario having it along with one for the Paper Mario: The Thousand-Year Door partners.
 * A few new character designs have been added, such as a purple, martial artist-themed Toad in Glitzville dressed in a coat and a guapi mao cap.
 * The whole party is visible while riding the Cheep Blimp.
 * More characters can be seen from behind, such as Mario's partners, unlike in the original, where they are shown in a frontal profile regardless of the camera angle.
 * Due to the widescreen resolution, the HUD elements, transitions, and some interiors have been redesigned to accommodate the extra horizontal space. Framing in several cutscenes and some background scenery has also been readjusted to go alongside these changes.
 * The character artwork in transitions is now shaded.
 * The soundtrack has been rearranged with new instrumentation and is now similar to the soundtracks of later entries in the Paper Mario series.
 * More visual aids for points of interest have been implemented, such as a sign that displays an icon with tacked papers above the door to the Trouble Center building, the pipe leading to Petal Meadows now resting on a grassy platform, and a set of easily visible footprints in eastern Rogueport that leads into a hidden alley.
 * The area the black chest face resides is now a fully 3D environment, rather than being a static background.
 * Bowser now has a rainbow effect when becoming gigantic on his levels.
 * When a black chest face curses Mario, he gets struck by lightning, while in the original, the screen flashes white while Mario is cursed.
 * Pa-Patch's eyepatch now always appears over his left eye, while in the original, it would always appear on the eye closest to the camera.
