The concept of spherical platforms originated from Super Mario 128, a GameCube tech demo shown at Nintendo Space World in 2000. Nintendo EAD Tokyo began developing Super Mario Galaxy after the release of Donkey Kong Jungle Beat in late 2004, when Shigeru Miyamoto suggested that Nintendo commission a large-scale Mario game. Certain levels use the motion-based Wii Remote functions. The player character is controlled using the Wii Remote and Nunchuk and completes missions, fights bosses, and reaches certain areas to collect Power Stars.
The levels consist of galaxies filled with minor planets and worlds, with different variations of gravity, the central element of gameplay. As Mario, the player embarks on a quest to rescue Princess Peach, save the universe from Bowser, and collect 120 Power Stars, after which the player can play the game as Luigi for a more difficult experience. It is the third 3D game in the Super Mario series.
Super Mario Galaxy is a 2007 platform game developed and published by Nintendo for the Wii.
