Which Nintendo Switch game introduced the desert kingdom called the Sand Kingdom?

The Nintendo Switch game that introduced the desert kingdom called the Sand Kingdom is Super Mario Odyssey.

Super Mario Odyssey is a 3D platform game released for Nintendo Switch in 2017. Mario travels between distinct kingdoms aboard the airship Odyssey, searching for Princess Peach after Bowser abducts her. The Sand Kingdom is one of the game’s major destinations and is centered on the desert settlement Tostarena.

The kingdom combines open areas, ancient ruins, icy hazards, and story objectives involving the region’s stolen artifacts. Mario can use Cappy, his sentient cap, to possess or “capture” certain creatures and objects, giving the game movement and puzzle abilities beyond traditional jumping.

The Sand Kingdom should not be confused with the Desert Land from Super Mario Bros. 3 or desert areas in other Mario games. Super Mario Odyssey’s kingdoms are named regions in a connected journey, and the Sand Kingdom is specifically associated with its desert setting and Tostarena town.
