The game was a critical and commercial success, having been hailed by critics as one of the greatest and most revolutionary video games of all time, and has won a BAFTA. It is listed among the top-rated games on various aggregate sites, and is the highest-ranked title on review aggregator GameRankings. The game is the eighth best-selling Wii game worldwide with sales of 12.69 million, as well as the best-selling 3D entry in theSuper Mario series. A direct sequel, Super Mario Galaxy 2, was released for the Wii in 2010.
Super Mario Galaxy is set in outer space, where Mario travels from galaxy to galaxy to collect Power Stars, which are earned by completing levels in galaxies or defeating enemies. Each galaxy contains a number ofplanets 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 is 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.
The game’s main hub is the Comet Observatory, a spaceship which contains six themed domes that provide access to the forty-two galaxies available in the game. Five of the domes end with a boss level in which the object is to defeat Bowser or Bowser Jr., which then allows the player to access the next dome. When the player first begins the game, access is available to only a few galaxies. However, as more Power Stars are collected, more galaxies become available to the player. When 120 Power Stars are collected, the player gains the ability to play through the game again as Mario’s brother Luigi. Gameplay is slightly different while playing as Luigi, as some obstacles can be harder or easier to overcome due to Luigi’s higher running speed and lower traction. Once 120 Power Stars are collected with both characters, the player is rewarded one additional challenge for Mario and Luigi to complete, as well as two commemorative pictures that can be sent to the Wii Message Board upon each brother completing the challenge.
Super Mario Galaxy has a co-operative two-player option called “Co-Star Mode”, in which one player controls Mario and a Star Pointer while the other uses only the Wii Remote to control a second Star Pointer on-screen to gather Star Bits and shoot them at enemies. Additionally, the second player can make Mario jump, or the height of Mario’s jump can be increased if the first and second player press the A button at the same moment. The second player can also prevent some enemies from moving by aiming the pointer star at them and holding the A button.
