History
The company was founded on 12 January, 2000, as a second-party developer for Nintendo. Their first game, Koto Battle: Tengai no Moribito (Japanese: コトバトル－天外の守人), was only released in Japan for the Game Boy Color on March 9, 2001. Their first Mario game, Mario & Luigi: Superstar Saga, has drawn heavy inspiration from Tomato Adventure, their second and last RPG game, which includes borrowed art style, strong resemblance of characters (such as Hermie III being based on the "Yadotsuri" enemy) and similar sound effects. In fact, some files from Tomato Adventures soundtrack are found unused in Mario & Luigi: Superstar Sagas files.
