I know that the Chinese zodiac has proclaimed 2013 the Year of the Snake, and the Geek Zodiac says it's the Year of the Pirate but guess what, they're wrong.  In a recent Nintendo Direct video Nintendo rebranded this year as the Year of Luigi, and has the game lineup to backup their claim (up?). 

Nintendo will be releasing no fewer than four titles focusing all on the leanest plumber of them all. Mustache sold separately:

• Luigi’s Mansion: Dark Moon: The game that kicks off the Year of Luigi launches March 24 and will include additional multiplayer modes beyond the previously revealed Hunter Mode. Up to four players with their own Nintendo 3DS systems can team up via local wireless, pair up in Download Play or connect over the Internet to escape each floor within the time limit in Rush Mode and search for the hidden ghost dogs in Polterpup Mode (up to four game cards may be required).
• Mario & Luigi: Dream Team: A new installment in the Mario & Luigi role-playing series is coming to Nintendo 3DS this summer. The game takes place inside the mind of a sleeping Luigi, who is a powerful, brave hero in his dreams.
• New Super Luigi U: To continue the fun of New Super Mario Bros. U for Wii U, Nintendo is letting Luigi take over in new downloadable content that is coming in the Year of Luigi that provides alternate versions of the game’s more than 80 stages. Players can freely change between the New Super Luigi U and New Super Mario Bros. U stages. These Luigi-focused stages provide a whole new level of game-play challenge and will be available for purchase as a single download.
• Fore!: Luigi and his Mushroom Kingdom neighbors are teeing up once again in Mario Golf: World Tour. The Nintendo 3DS game includes both simple controls and a deeper experience for golf fans, plus courses that range from traditional to those inspired by the Mushroom Kingdom. The game launches this summer.
