Mario Kart Arcade GP 2 is the sequel to Mario Kart Arcade GP, making it the second arcade title in the Mario Kart series. It is extremely similar to the first, to the point of featuring all courses and playable characters from it. However, it adds four new courses for two new cups: Yoshi Park 1 and Yoshi Park 2 for the Yoshi Cup, and Stadium Arena and Waluigi Stadium for the Waluigi Cup. Two new playable characters were also added: Waluigi, a Nintendo character and perhaps the more obvious choice, and Mametchi, a Bandai character from the digital pet toy Tamagotchi, due to Namco and Bandai's recent merge. The same technical aspects of the previous game return, including the magnetic Mario Card, which is used for saved game data.
