Mario Kart Live is an innovative racing game that combines real-life remote-controlled cars with augmented reality. Players control a physical kart that moves around their home while using a Nintendo Switch to view the race track on the screen. The game features familiar characters like Mario and Luigi, and players can set up custom tracks using household items. The game includes various modes, such as Grand Prix and Time Trials, allowing players to compete against AI or friends. As players race, they can collect power-ups and use them to gain an advantage, just like in traditional Mario Kart games.
