The guys of Gaming Boulevard review the Wii U download version of New Super Mario Bros. Wii and concluded:
New Super Mario Bros. Wii offers a lot of fun and great content for Super Mario fans. It has the right difficulty and has some fun new worlds and items to mess around with. If you missed the original game and own a Wii U, it’s certainly worth downloading. If you already own the game, there’s no need to download it, it doesn’t offer anything new. New Super Mario Bros. Wii is the perfect game for a fun evening with friends or to have some classic Super Mario fun on your own.
