Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey

Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey (known as Mario & Luigi RPG3 DX in Japan) is an upcoming game for the Nintendo 3DS, set to be released in Japan on December 27, 2018, in the Americas on January 11, 2019, in Europe on January 25, 2019, and in Australia on January 26, 2019. It was announced in a Nintendo Direct on March 8, 2018. The game is an enhanced remake of the 2009 Nintendo DS game Mario & Luigi: Bowser's Inside Story. The remake also features another story where Bowser Jr. takes action on an adventure, similar to Minion Quest: The Search for Bowser, with two important differences shown so far: a slot for an additional second-in-command who will have its own actions just like Bowser Jr. as well as formations for the troops.

List of changes

 * Badges appear to be obtained much earlier in the remake. Instead of being received from Princess Lipid in the Flab Zone, they are shown to be in the battle with Scutlet in the Flame Pipe, implying that they were obtained sometime earlier.
 * Like in Mario & Luigi: Dream Team, players can choose whether they are right or left handed, altering the position the 3DS needs to be in during giant boss battles.
 * Two new characters are introduced in Bowser Jr.'s Journey.
