NZ Gamer - To commemorate the thirtieth anniversary of Luigi’s first appearance in the 1983 arcade game Mario Bros, Nintendo has dubbed 2013 the Year of Luigi. This means all sorts of Luigi themed events, games, and collectibles spread out across the year.
Among them? New Super Luigi U, a “full game DLC” package for New Super Mario Bros U that finally lets the tall, green-clad brother be the hero who saves Princess Peach. Rather than just being a standard content pack with a few extra levels, Luigi U lets you play through Mario U in its entirety as Luigi, with all 82 levels redesigned to offer new challenges suited to Luigi’s unique abilities.
