The player starts out with only Mario, but unlocks Princess Peach, Luigi, and even Bowser through the game, and can change between them at any time. The gameplay is similar to the classic Super Mario games, but with the aesthetic qualities of the Paper Mario series, RPG-like elements like character dialogue and puzzles, and a blend of 2D and 3D platforming.
Super Paper Mario is a RPG-styled platformer developed by Intelligent Systems and published by Nintendo for the Wii.
