True fans know that Luigi has long been the superior brother. Well, now Nintendo has acknowledged this fact by proclaiming 2013 as Year of Luigi. To commemorate Luigi's ascendancy over his lesser brother, Mario, Nintendo has announced Mario & Luigi: Dream Team and Mario Golf: World Tour. Dream Team is the 4th in the popular Mario & Luigi RPG series. The game focuses on Luigi dreaming an adventure, similar to Mario in Super Mario Brothers 2 USA.
Mario Golf: World Tour is a sequel to Camelot's GameCube classic golf game. Camelot, the makers of the Shining Force series, has some experience in golf. Camelot's first game was Everybody Golf all the way back in 1997, and their most recent was We Love Golf in 2007. Mario Golf 3D showed off greatly improved visuals over the GameCube game.
Nintendo showed more Luigi's Mansion 2 as well, from ghost puppy tracking to its online co-op gameplay. The game releases on March 24th in North America, and March in Europe.
Finally, Nintendo announced an expansion pack to New Super Mario Brothers U, a complete remake of all 80 levels in the game, playable only by Luigi. The expansion DLC contains only Luigi and Luigi levels, and even modifies interface elements to accommodate Luigi's green color scheme. As such, the expansion is titled "New Super Luigi U", as there is only Luigi and not his brother.
So, Luigi fans, celebrate the Year of the Superior Brother, 2013!
