Super Circuit is a kart racing video game in which the player races in a kart against other teams in different courses. The game screen indicates the current standings in a race, the current speed of the player's kart and incoming weapons. Like in the previous installments, players can pick up item boxes to receive a randomly selected item and use it to impede the opposition and gain the advantage. Some items, such as shells and bananas, allow the player to hit others to slow them down, while other items, such as the star power-up, render them temporarily invincible to attacks. This is the second Mario Kart game to include coins, which increases the top speed of the karts.

In the Japanese version of Paper Mario: The Thousand-Year Door, Vivian(pictured) was depicted as a male who identified as a female, openly stated in her character description.

Rosalina is always depicted as right-handed in artwork, but she is always depicted as left-handed in-game, with a few exceptions. In Mario Golf: World Tour, the player can choose if Rosalina is left- or right-handed, and Rosalina holds her wand with her right hand during cutscenes in Super Mario Galaxy.
