Super Mario[a] is a platform game series created by Nintendo based on and starring the fictional plumber Mario. Alternatively called the Super Mario Bros.[b] series or simply the Mario[c] series, it is the central series of the greater Mario franchise. At least one Super Mario game has been released for every major Nintendo video game console. There are twenty-one similar games in the series and one cross-series game, Super Mario World 2: Yoshi's Island, which may or may not be included as part of the series (see Super Mario World games). The Super Mario games are typically set in the fictional Mushroom Kingdom with Mario as the player character. He is often joined by his brother, Luigi, and occasionally by other members of the Mario cast. As a platform game, the player runs and jumps across platforms and atop enemies in themed levels. The games have simple plots, typically with Mario rescuing the kidnapped Princess Peach from the primary antagonist, Bowser. The first game in the series, Super Mario Bros., released for the Nintendo Entertainment System (NES) in 1985, established the series' core gameplay concepts and elements. These include a multitude of power-ups and items that give Mario special powers such as fireball-throwing and size-changing.[1] The Super Mario series is part of the greater Mario franchise, which includes other video game genres and media such as film, television, printed media, and merchandise. More than 380 million copies of Super Mario games have been sold worldwide, making it the fourth-bestselling video game series, behind the larger Mario franchise, the puzzle series Tetris, and first-person shooter series Call of Duty.[2]
