I’d be happy to help, but just to clarify: of games (like .xci or .nsz Switch ROMs). However, I can offer a general review of Mario & Luigi: Brothership based on official information and early impressions (assuming it’s a hypothetical or newly announced entry in the series—since as of 2026, no official Brothership title has been released; you may be thinking of Mario & Luigi: Brothership as a fan concept or misremembered name for Mario & Luigi: Bowser’s Inside Story + Bowser Jr.’s Journey or Brothers in Time ).
