Buying physical copies of games from retailers also ensures you're getting a legitimate copy of the game.

"Mario & Luigi: Brothership" is a role-playing game developed by AlphaDream and published by Nintendo for the Nintendo 3DS. However, if there's a version or a related game for the Nintendo Switch, details might be limited or not widely available as of my last update.

Purchasing games through official channels supports the developers and the gaming industry as a whole.
