Super Mario is a series of platform video games created by Nintendo featuring their mascot, Mario, an Italian plumber. The Super Mario games follow Mario's adventures in the fictional Mushroom Kingdom, usually with Mario as the player character. He is usually joined by his brother, Luigi, and occasionally by other members of the Mario cast. As in platform video games, 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 title in the series, Super Mario Bros., was released in 1985
