Luigi's Mansion, known as (ルイージマンション Ruīji Manshon?) in Japan, is an action-adventure game published by Nintendo for the GameCube. It was the first game in the Mario franchise to be released for Nintendo GameCube. It was released in Japan on September 14, 2001, in North America on November 18, 2001, and in Europe on May 3, 2002. The game was a launch title for the GameCube, and the second title in the Mario franchise where Luigi is the main character, instead of Mario, the first and third being Mario is Missing! and Luigi's Mansion: Dark Moon, respectively.

The game takes place in a haunted mansion when Luigi wins a contest that he never entered. He told his brother to meet him there to celebrate his victory. Luigi is searching for his brother, Mario, who came to the mansion earlier, but went missing. To help Luigi on his quest, an old professor named Elvin Gadd or E. Gadd has equipped him with the "Poltergust 3000", a vacuum cleaner used for capturing ghosts, and a "Game Boy Horror", a device used for communicating with E. Gadd. He also uses it as a map and to examine ghosts. less
