Super Mario Galaxy

Super Mario Galaxy is a 3D platform game developed by Nintendo EAD Tokyo and published by Nintendo for the Wii. It was released in most regions in November 2007, and is the third 3D original platformer in theMario series, after Super Mario 64 and Super Mario Sunshine. The game follows the protagonist, Mario, on a quest to rescue Princess Peach from the game's primary antagonist, Bowser. Levels are galaxies filled with minor planets and worlds, while gameplay is updated with gravity effects and new power-ups.

Super Mario Galaxy was first shown at E3 2006 and enjoyed a high level of pre-release awareness. The game has been hailed by several gaming websites as one of the best video games of all time and has won a BAFTA. GameRankings lists the game as the best reviewed Wii game and the second best reviewed game of all time. The game is the ninth best selling Wii game worldwide with sales of over 8.84 million. The sequel, Super Mario Galaxy 2, was announced at E3 2009, and was first released in May 2010. In 2011, Super Mario Galaxy was added to the Nintendo Selects collection of games.

Super Mario Galaxy is set in outer space, where Mario travels from galaxy to galaxy in order to collect Power Stars, which are earned by completing galaxies or defeating enemies. Each galaxy contains a number of planets and other space matter for the player to explore. The game uses a new physics system that allows for a unique feature: each celestial object has its own gravitational force, allowing the player to completely circumnavigate rounded or irregular planetoids, walking sideways or upside down. The player can usually jump from one independent object and fall towards another one nearby. Though the main gameplay and physics are in 3D, there are several areas in the game in which the player's movements are restricted to a 2-dimensional plane, an element reminiscent of 2D Mario games.
