One of the first-gen Wii U title is a Western-outsourced spin-off of Super Mario Bros. A M-rated hack-n-slash starring the antagonistic Bowser, the lead designer describe it as a "darker, violent, badbutt action game that is the antithesis of the Mario games. Something that older, action-game-loving people could enjoy." and justify the jarring tone shift with "I think it's important to give Bowser a total badbutt edge to be a potentially M-Rated game.". The game flops miserably, leading Nintendo to cancel an unannounced localisation of Mother 3 for the 3DS e-shop in order to recoup costs.
