Mario & Luigi: Superstar Saga + Bowser's Minions

Mario & Luigi: Superstar Saga + Bowser's Minions (called Mario & Luigi RPG1 DX in Japan ) is an upcoming game for the Nintendo 3DS, set to be released in North America and Europe on October 6, 2017. It is an enhanced remake of the 2003 Game Boy Advance game, Mario & Luigi: Superstar Saga. The game also has an added story called Minion Quest: The Search for Bowser. The game is set to have amiibo support for the Minion Quest mode, where the Koopa Troopa, Goomba, and Boo amiibo are to be compatible. The game is set to be the first remake of the Mario & Luigi series, the third game in the series to be released for the Nintendo 3DS, and the sixth game in the series overall. Despite being a Nintendo 3DS game, it is set to only be playable in 2D.

Mario & Luigi: Superstar Saga
The remake of Mario & Luigi: Superstar Saga has updated graphics, soundtrack and controls, looking visually similar to Mario & Luigi: Dream Team and Mario & Luigi: Paper Jam. The story appears to be the same as it was in the original game. However, some additions and alterations to the gameplay have also been made.

List of changes

 * Mario and Luigi will now jump twice on an enemy if a solo jump's action command is entered correctly, just like in previous installments since Mario & Luigi: Bowser's Inside Story.
 * The Emergency Guard from Mario & Luigi: Paper Jam is added.
 * The Solo-Attack-Command Block is replaced with separate Command Blocks for Jump-, Hammer- and Hand-Attacks.
 * Hoohooros now drops a new piece of gear for Mario called the Hoohooros Slacks.
 * Advanced Bros. Attacks are now separately selected and cost more Bros. Points to use.
 * Mario & Luigi now make sounds whenever they are hit in battle as well as during Bros. Attacks.
 * The level of an enemy is now displayed next to their name when targeting them.
 * The game now has a lot of new features due to the added second screen.
 * Mario & Luigi's passports showing their level and stats displayed in battle
 * A tutorial for attacks displayed in battle similar to the one in Mario & Luigi: Paper Jam.
 * In the overworld, the touch screen can be used to switch between moves like the High Jump or the Spin Jump.
 * The player can also press a button on the touchscreen to display a map where they can also put markers.
 * Heart Blocks are present in every version of the game unlike in the original, where only the Japanese version featured them.
 * Cutscenes can be sped up with, or possibly with the icon on the touch screen.
 * Mario & Luigi's positions can no longer be switched manually. Instead, they will switch automatically when selecting a move.
 * Pressing the X-Button in the overworld will make both Bros. jump simultaneously.
 * The line of the Koopa Troopa originally telling the player about switching places was changed to inform about this mechanic.
 * The menu screen features a guide option, showing how certain actions are performed similar to Mario & Luigi: Paper Jam.
 * This function is also available in battle via the bottom screen.
 * The percentage of beans and ?-Blocks found can also be viewed in the menu screen along with a summary of the current story.
 * A sound player was added. Unlike in previous entries, it's not accessible from the title screen but from the in-game menu screen.
 * Options have also been moved from the title screen to the menu screen.
 * Visible on the menu screen there are some Battle Cards from Mario & Luigi: Paper Jam. It's currently unknown if these are only a callback or if they will appear in the game like they did in Mario & Luigi: Paper Jam.
 * The time limit to collect ten Hoohoo Spirits in Hoohooros's minigame has increased from 30 seconds to 35.
 * "Toad Town Square" was renamed to "Peach's Castle".
 * Many character sprites are apparently derived from the sprites of Mario & Luigi: Dream Team and Mario & Luigi: Paper Jam, causing their appearance to be different with respect to the one of the original game.
 * Troopeas are bipedals rather than quadrupedals.
 * Iggy Koopa has the modern design with the pineapple-like haircut instead of the colored mohawk.
 * The NPC Koopa Troopas from the Koopa Cruiser no longer wear flight uniforms.
 * The Toads in Peach's Castle are now regular Toads with differently coloured spots and vests rather than differing in height and clothing.
 * The cannon that Bowser gets stuck in during Stardust Fields now flies away upon firing him out, rather than blinking away after the camera pans back to Mario and Luigi.
 * Several cameos have been added to the Mario Bros.' House
 * There is now a trophy from Mario Kart 8 on a shelf and a Wii Wheel hanging next to it.
 * Mario's tennis racket and golf club can be seen on a shelf above and leaning on Mario's bed, respectively.
 * Mario's Cap is now on the clothing line outside of the house rather than on the coat-stand inside, fixing a minor continuity issue when Mario puts on his clothes. In the original game, his cap suddenly appears on his head once he's all dressed up.
 * A carpet in front of the Bros.' beds looking like a Yoshi Egg has been added.
 * A pendulum clock has been added to the wall.

Minion Quest: The Search for Bowser
This new story involves Bowser's minions battling the enemies of the Beanbean Kingdom to rescue Bowser, after he is knocked out from the Beanbean Border, led by Captain Goomba. The battles are the two armies automatically fighting against each other, though the player can choose which characters to send in and what actions to take, the latter of which costs CP. At the end of a battle, if any of the opponent's allies had survived, they will join the player's team. There are three types of troopers: Melee (who only fight physically), Ranged (who fight exclusively with projectiles), and Flying (physically fighters who fly).
