New Super Mario Bros. U Deluxe

New Super Mario Bros. U Deluxe is a side-scrolling 2.5D platform game released on the Nintendo Switch worldwide on January 11, 2019. It is a port of the Wii U launch title New Super Mario Bros. U. It contains both the base game and the New Super Luigi U DLC. Mario, Luigi, Yellow Toad, Blue Toad (both generically named Toad in this game), and Nabbit all return as playable characters from the original Wii U title while this game introduces a new playable character, Toadette, who makes her playable debut in the New Super Mario Bros. games. She has a unique form known as Peachette, which she obtains after grabbing a new item called the Super Crown. The Peachette form grants her abilities similar to that of Princess Peach and Princess Daisy.

Differences from New Super Mario Bros. U and New Super Luigi U

 * Toadette is added as a new playable character.
 * The Super Crown is added as a new power-up exclusively for Toadette. Toadette becomes Peachette after touching the Super Crown, which allows her to float and double jump similar to the Flying Squirrel form (but with a more versatile aerial movement), and avoid falling into pits. However, unlike the Flying Squirrel form, she cannot cling on to walls and she will not descend significantly when turning. Other characters cannot pick it up, merely passing through it without getting rewarded.
 * Before fighting Bowser's final phase as Peachette, Peach will notice Peachette from her tower looking confused just before the cage slams shut.
 * When playing as Toadette, all Blocks containing 1-Up Mushrooms instead contain 3-Up Moons.
 * Toadette and Nabbit have swimming properties like the Penguin Suit, no matter what form they have.
 * Toadette and Nabbit are less slippery than Mario, Luigi, and Toad. Even while running, they will stop sooner and are less likely to fall into pits. They are also resistant to slipping on ice.
 * Both the New Super Mario Bros. U and the New Super Luigi U levels start with 100 additional seconds on the timer when playing as either Toadette or Nabbit, though no bigger time bonus is given when both of them are being played.
 * Yellow Toad and Blue Toad share a character slot, and are both referred to as simply "Toad". To switch between them, the player needs to hold the L or ZL button (SL button when playing with a single Joy-Con) while choosing said playable character.
 * Blue Toad is absent from the introduction and ending cutscenes, with Toadette appearing instead. Yellow Toad is the one who looks at the Koopas' escape in the ending (Blue Toad does this in the original versions).
 * The game has a higher resolution, being displayed in native 1080p in TV mode, and 720p in Handheld and Tabletop modes, as opposed to the dynamic 1080p and 720p resolutions of a TV connected to a Wii U, and a Wii U GamePad, respectively.
 * It is possible to play as Luigi, Toad, Toadette, and Nabbit in single player in this game's version of the main mode of New Super Mario Bros. U, as well as this game's version of New Super Luigi U (Mario remains non-playable in New Super Luigi U, and Miis have not been seen as playable in either of the aforementioned modes). The original release of New Super Mario Bros. U only allows single players to play as Mario in the story mode, while the original release of New Super Luigi U restricts single players to Luigi, Nabbit (except in Flying Squirrel Ovation), and Mii characters (only in Flying Squirrel Ovation).
 * As a result, Nabbit can now be played within the New Super Mario Bros. U story mode levels.
 * Nabbit has new voice clips that are similar to Toads.
 * Nabbit can bounce off Yoshis since he cannot ride them, unlike the original game where he simply goes through them.
 * Nabbit can now carry objects.
 * There is now a hint button on the menu.
 * Character selection icons now use their updated artwork. Toadette and Nabbit are also labeled as "Easier" and "Easiest" ("Easy" and "Very Easy" in the British English version) respectively.
 * The title screen uses the same ground as the New Super Luigi U title screen with Nabbit included.
 * New Super Mario Bros. U Deluxe is incompatible with Miiverse. The service ended prior to New Super Mario Bros. U Deluxe's release, and is not available for the Nintendo Switch.
 * When entering a world, the name of the map has a different banner design, with 2D artwork of blocks in outlines.
 * The loading screens background uses different 2D icons.
 * In this game's version of New Super Mario Bros. U, the button tabs on the map are red instead of blue. This game's versions of both New Super Mario Bros. U and New Super Luigi U use button icons of the Switch controllers. Additionally, the player can also use to open the menu.
 * Challenges make a return; however, Boost Mode challenges are removed due to Boost Mode being incompatible with the Nintendo Switch controls.
 * The challenges menu has been redesigned.
 * The game uses HD rumble, unlike the original game which uses simple rumble.
 * In the pause menu during levels, buttons on the controller can be remapped.
 * On the pause screen, characters can be changed on the map screen.
 * The jump controls are now shared with the mid-air spin, performed by pressing or  in mid-air.
 * A neon Nintendo Switch console appears in the Records Toad House, which plays a music box rendition of the game's credits theme while the credits roll.
 * The Records Toad House pages now resemble a map marked with a red stamp depicting a silhouette of Nabbit's ears. "Records" is now renamed to "Mario U Records" and "Luigi U Records" in the American English version, depending on the game being played. As Boost Mode has been removed, the records for "Distance on Boost Blocks" and "Distance on Mini Boost Blocks" have been replaced with "Times Companion Lifted" and "Synchronize Ground Pounds" respectively, along with updated icons.
 * In the Baby Yoshi minigame for the Power-Up Toad House, the Glowing Baby Yoshis' Toad icon has been updated to resemble Toad's 2D artwork from Super Mario 3D World but with red spots.
 * When playing as Nabbit in single player, completed level spaces turn purple instead of blue.
 * In both the ending and the cutscene where Peach is being rescued, Nabbit always appears in the background, regardless of what character(s) was/were used in the final boss battle.
 * When playing as Luigi in New Super Mario Bros. U, a red-colored Super Guide Block appears and summons a computer-controlled Mario to clear the level in place of Luigi.
 * The buttons for Challenges, Boost Rush, and Coin Battle on the main menu have artwork of Mario thinking, Mario running, and a Star Coin respectively, replacing the Super Mario Bros. sprites seen on the buttons in the original New Super Mario Bros. U.
 * In New Super Mario Bros. U, the red Toad Houses with the shuffle mini-games have some items changed. Several Super Stars have been replaced by Super Crowns, while in New Super Luigi U, the 1-Up Mushrooms are now 3-Up Moons.
 * Enemy Courses now have a chance to hold a Super Crown or a Penguin Suit.
 * In New Super Mario Bros. U the stars on the player's profile will remain shiny, even if the player activated the Super Guide before.
