Även om det var Next Level Games som utvecklade Luigi's Mansion 2, hindrade det inte Shigeru Miyamoto från att kliva in och styra upp saker och ting. Bland annat ska han ha ratat studions ursprungliga bossar man designat för spelet.
Bryce Holliday, spelets regissör, berättar i en intervju med IGN:
"At one point he threw out all the bosses of the game and made us start over. From our angle that was kind of a tea-table-flip. But maybe it just had bad legs and was wobbling or something. He often challenged us to not go with our first idea, or to experiment further on different things and then cherry-pick our best ideas."
