Ken McKown writes: This is the year of Luigi; at least that is what Nintendo claims. With New Super Mario Bros. U still being one of the sole reasons to own the big N’s new console, it is only fitting that Mario’s brother gets the respect he deserves. New Super Luigi U is really a first for Nintendo. This hefty DLC package basically re-skins the entire New Super Mario Bros. U experience, putting Luigi front and center. Those concerned that the same levels and challenges are just being recycled can lay those worries to rest; this is one expansion that delivers on its promise.
