Densetsu no Quiz Ou Ketteisen is a GameCube video game released exclusively in Japan in 2005. The game's title translates to The Legend of the Quiz Tournament of Champions in English. It was one of the few games to make use of the GameCube's Microphone (which it came bundled with), which in America came with Mario Party 7 and Odama. The game is a quiz title, and it is unknown why it wasn't released in America and why it was rated C by CERO.
