[Platformer - Wii] Super Mario Galaxy

Super Mario Galaxy (スーパーマリオギャラクシー ,Sūpā Mario Gyarakushī^?) is an award-winning 3D platform game developed by Nintendo EAD Tokyo and published by Nintendo for the Wii.
It was released in Japan on November 1, 2007, the United States on
November 12, 2007, Canada on November 14, 2007, Europe on November 16,
2007, Australasia on November 27, 2007 and South Korea on September 4,
2008. It is the third 3D platformer in the Mario 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 is one of the most critically acclaimed titles of all time, and has won numerous "Game of the Year" awards including a BAFTA.
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 quests 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, a feature seen previously
in Super Mario World 2: Yoshi's Island.
The player is usually able to jump from one independent object and then
fall towards another one close by. 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 axis, an element reminiscent of 2D Mario games.
