Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey launches exclusively for the Nintendo 3DS family of systems in 2019.
Finally, following the hit sequel, Luigi's Mansion is being remade on the 3DS. In the game, Luigi enters a mansion filled with ghosts to save his brother and has to suck up all the ghosts in sight and face a handful of inventive bosses that haunt the mansion.
The Luigi's Mansion remake is coming out some time in 2018.
The game has not been given a release date, but instead has been slated for release this year. If this game includes any additional significant new content, Nintendo isn't quite ready to reveal what that content may be at this time.
The trailer for the game showcased a remake of the game along with the new Bowser's Jr's Journey sidestory. Of course, you could always boot up your Nintendo GameCube to play the original. You'll also be able to utilize an in-game map that will work with the 3DS touchscreen.
