by Nintendo. Created by prominent game designer Shigeru Miyamoto, Luigi is portrayed as the slightly younger but taller fraternal twin brother of Nintendo's mascot Mario, and appears in many games throughout the Mario franchise, frequently as a sidekick to his brother.
Luigi first appeared in the 1983 arcade game Mario Bros. as the character controlled by the second player, and retained this role in Super Mario Bros., Super Mario Bros. 3, Super Mario World, and other titles. The first game where he was available as a primary character was Super Mario Bros. 2. In more recent appearances, Luigi's role became increasingly restricted to spinoffs such as the Mario Party and Mario Kart series, though he has been featured in a starring role on three occasions: first in the 1991 educational game Mario is Missing, in Luigi's Mansion for the Nintendo GameCube in 2001, and in Luigi's Mansion: Dark Moon for the 3DS.
Originally developed as a palette swap of Mario with a green color scheme instead of red, Luigi has since developed a personality and style of his own. As his role in the Mario series progressed, Luigi evolved into a physically distinct character, taller and thinner than his brother. Nintendo has called 2013 "The Year of Luigi" to commemorate the thirtieth anniversary of the character's existence. Correspondingly, games being released in 2013 emphasise Luigi, such as Luigi's Mansion: Dark Moon, Mario & Luigi: Dream Team and the level pack New Super Luigi U for New Super Mario Bros U.
