About Super Mario Galaxy 2

See also: Gameplay in Super Mario Galaxy

The gameplay of Super Mario Galaxy 2 is similar to that of the first Super Mario Galaxy, with a focus on platforming based on and around 3D planets (referred to collectively as galaxies)^[7] with varying themes, sizes, and landscapes. The player controls Mario (or in other moments of the game, his brother Luigi^[8][9]) who has a variety of physical abilities. Like the original, the objective of the game is to travel to the various galaxies and collect Power Stars, which are awarded by completing levels and accomplishing tasks and are used to open access to later levels. The game retains some gameplay mechanics introduced in the original, such as the blue Star Pointer that allows the player to pick up Star Bits and shoot them at enemies, levels that restrict movement to a 2D plane, balance ball levels, and gravity-reversing background arrows.^[10]

Super Mario Galaxy 2 provides the player access to the game's galaxies through means of a map system similar to that in previous Mario games such as Super Mario World and New Super Mario Bros. Wii.^[11][12] This is navigated via a mobile planet called Starship Mario (so named because it is shaped like Mario's head^[10]) that serves as a hub world, which can be visited anytime and is expanded upon when new abilities are unlocked.^[13] The game contains forty-nine galaxies allotted among seven different regions in the universe (called "worlds"), the general difficulty progressively increasing in each world. The first six worlds end with a boss level against Bowser or Bowser Jr. that, when conquered, allow the player to access the next world. When the player collects all 120 Power Stars, 120 Green Star levels are unlocked. These levels contain Green Stars that are hidden or are placed in hard-to-reach areas, focusing on heavy exploration and precision that could result in instant death if the player fails. Acquiring all 120 Green Stars awards the player with the final, forty-ninth galaxy with two new challenges that are considered exceptionally difficult.^[14] Super Mario Galaxy 2 contains 242 unique Power Stars to collect overall.^[15]
Most of the levels in Super Mario Galaxy 2 each offer a unique task based around its theme, and many focus on dynamic environments that change or alternate between various states. For example, some environments change to the beat of the background music, such as sudden shifts in the direction of gravity or the appearance or disappearance of platforms; and others feature a special switch that temporally slows down time. Prankster Comets, which were featured in the original game and cause variation and tougher challenges in levels, no longer appear randomly in visited galaxies but instead require the collection of a Comet Medal in that galaxy in order for it to appear.^[16] In addition, Prankster Comets have become more general and offer any number of variations: while Super Mario Galaxy offered only five mutually exclusive variations, the Prankster Comets in Super Mario Galaxy 2 range to any number of challenges that often mix or overlap, such as destroying all the enemies, collecting 100 Purple Coins, completing the level within a time limit or while avoiding Cosmic Clones (doppelgängers of Mario that pursue and imitate all the player's actions). As a result, both the dynamic environments and the Prankster Comets often create challenges with puzzle elements, requiring precision and strategy in order to overcome them.

All the original transformations in Super Mario Galaxy return except for Ice Mario and Flying Mario, along with some new power-ups and items. These include the Spin Drill, which allows the player to burrow through planets and emerge out the other side;^[10] Rock Mario, which allows the player to smash through barriers;^[17] and Cloud Mario, which allows the player to create temporary platforms in midair.^[18] Mario is able to ride the dinosaur Yoshi, who is available in certain levels. When riding Yoshi, the player's blue Star Pointer is replaced by a red dot, which allows the player to point at various objects and manipulate them with Yoshi's frog-like tongue.^[19] Yoshi can use his tongue to swing across gaps, pull levers, and gulp enemies, or spit them back out as projectiles.^[10] There are three different power-up fruits available for Yoshi to eat that grant him temporary abilities, such as speed boosts, the ability to inflate like a balloon, or the power to reveal secret paths.^[20]

Because of the game's advanced difficulty over the original, Super Mario Galaxy 2 offers some features that assist inexperienced or frustrated players. The most notable is the Cosmic Guide, similar to New Super Mario Bros. Wii's 'Super Guide' feature. The Cosmic Guide appears if the player has failed during a particular level a certain number of times, and allows the player to give computer control over Mario in order to complete the level if necessary. The drawback is that the player is awarded a Bronze Star, requiring them to complete it themselves in order to earn a Golden Power Star.^[21] There are also monitors called "Hint TVs" that will demonstrate how to perform a specific move or optimal ways of using a power-up.^[22]
Multiplayer gameplay has been expanded upon over the original. In Super Mario Galaxy, another player could use a second Wii Remote to control a second Star Pointer and assist Mario by grabbing onto enemies or collecting and shooting Star Bits. In Super Mario Galaxy 2, the second player now controls an orange Luma who retains all the original abilities, but can also physically attack enemies and collect items and power-ups, making the player's involvement more useful.^[21]

The plot of Super Mario Galaxy 2 is a follow-up of the original. Princess Peach invites Mario to share some cake at the Star Festival, a time when Star Bits rain down from the skies over the Mushroom Kingdom. On his way, Mario finds a Luma, who immediately befriends him and grants him the ability to spin. Shortly thereafter, Mario's archnemesis Bowser, who has grown to an immense size (after swallowing Grand Stars, unbeknownst to Mario at this point), invades and attacks the Mushroom Kingdom. Kidnapping the princess, Bowser escapes into outer space to create his empire at the center of the universe. After launching into outer space, Mario is given control of Starship Mario, a mobile planetoid in the shape of his head, made by a crafty Luma mechanic called Lubba, powered by Power Stars, and piloted by other Lumas; his mission is to fly across the universe in pursuit of Bowser and the Princess and to help Lubba find the lost Lumas that were part of Bowser's plot. Along the way Mario meets new Lumas and joins up with his companion Yoshi.^[23]
Upon collecting enough Power Stars, Starship Mario reaches Bowser's main fortification, draining energy from what appears to be a comet. Mario infiltrates the castle and defeats Bowser, retrieving the last Grand Star. Rosalina and her Comet Observatory from the first Super Mario Galaxy appear before Mario and Peach. Rosalina thanks Mario for watching over the Luma that he had found, and the Luma returns to the Comet Observatory along with Mario's hat. Mario and his companions return to the Mushroom Kingdom.

Shortly after Super Mario Galaxy was completed, Shigeru Miyamoto approached the development team and suggested that a follow-up be produced. The game was originally planned just to do variations on the original game's planets and call the game "More Super Mario Galaxy", (it was dubbed "Super Mario Galaxy 1.5" during early development), with a projected development time of approximately a year. The first elements that were implemented were anything that was scrapped from the original game, either to ensure game balance or simply because of time constraints, such as Yoshi and the concept of a planet shaped like Mario's head. Over time, more and more new elements and ideas were brought into the game, and it was decided that the game would be a fleshed-out sequel rather than a slightly modified follow-up. Thus, development took two and a half years. Takeshi Hayakawa, the lead programmer for Super Mario Galaxy 2, created a development tool that allowed different staff members, including visual and sound designers, to easily design and create stages without waiting for programmers, many of which were incorporated into the final game.^[24] In order to help distinguish Super Mario Galaxy 2 from its predecessor, the staff originally wanted the whole game to revolve around the concept of "switching," in which the game's environments would dramatically change under certain conditions. This concept ended up being particularly difficult to implement full-scale, so was relegated to only certain levels.^[25] Game tutorials were confined to an optional system called the "Tip Network" in order to benefit players already familiar with the original game.^[26] Miyamoto compared Super Mario Galaxy 2 to The Legend of Zelda: Majora's Mask, in that both games use the same engines as their predecessors, yet build upon their foundations.^[27]
Super Mario Galaxy 2 was revealed at the Electronic Entertainment Expo 2009 on June 2. In Miyamoto's private conference, it was stated that the game was very far along in development, but its release was held back to mid-2010 due to New Super Mario Bros. Wii's release in late 2009. Miyamoto also stated that the game has 95–99% new features, with the rest being previous features introduced in Super Mario Galaxy.^[28] With regard to the original game, Nintendo of America President and CEO Reggie Fils-Aime stated in an interview that the sequel would be more challenging,^[29] and Miyamoto said in a Wired interview that the game would have less focus on plot.^[30] Miyamoto initially hinted that the game might utilize the "Super Guide" feature, introduced in New Super Mario Bros. Wii, into the game,^[31] and this was confirmed by Nintendo's Senior Manager of Product Managing, Bill Trinen, who claimed that the feature is implemented differently compared to what New Super Mario Bros. Wii offered. The feature is called Cosmic Guide, where the Cosmic Spirit (Rosalina) takes control of Mario.^[32]
The game made its playable debut at the Nintendo Media Summit 2010 on February 24, 2010, when a second trailer for the game was released, and its North American release date on May 23, 2010 was finally announced.^[33][34] The Japanese, European and Australian versions of the game came packaged with an instructional DVD manual, explaining the basic controls, as well as showing advanced play.^[35]

As with the original Super Mario Galaxy, Super Mario Galaxy 2 features a musical score written for and performed by a symphony orchestra. Early in the development process, when the concept of "Super Mario Galaxy 1.5" was being considered, there were no plans to use different music from the first Super Mario Galaxy. However, as the game evolved, the sound team, headed by Mahito Yokota, realized they needed new music that fit with the new gameplay mechanics that were being added. Although they were hesitant to use an orchestra again because of recording difficulties, general producer Shigeru Miyamoto gave permission immediately - according to Yokota, he felt that players would be expecting an orchestral soundtrack. Miyamoto also apparently suggested that players would want to hear arrangements from Super Mario Galaxy, which is why the soundtrack is a mixture of brand new pieces and arrangements of themes from Galaxy as well as many past installments in the Mario series.^[36] Ryo Nagamatsu, who worked previously on Wii Sports Resort and New Super Mario Bros. Wii, contributed nine pieces to the soundtrack.
Nintendo composer Koji Kondo recruited 60 musicians for the orchestra, ten more than the number of musicians used for the original game's score, with an additional 10 musicians providing a big band style of music with trumpets, trombones, saxophones and drums. The orchestral performances were conducted by Taizo Takemoto, renowned for his work on the Smash Bros. Concert in 2002, while Kondo served as an advisor and supervisor, and contributed five pieces to the soundtrack.^[37]
The soundtrack is currently available on a 2-disc set to members of the Japanese Club Nintendo as a reward. It can be acquired at the cost of 500 Star Points, though members who register a product code after purchasing Super Mario Galaxy 2 can obtain it for 300 Star Points.^[38] There have been no announcements about the soundtrack's availability in other territories
Super Mario Galaxy 2​ (スーパーマリオギャラクシー2, Sūpā Mario Gyarakushī Tsū^?) is a platforming video game developed by Nintendo for the Wii. It was first announced at E3 2009 and is the sequel to Super Mario Galaxy. It was released in North America on May 23, 2010,^[1] in Japan on May 27, 2010, in Europe on June 11, 2010, and in Australia on July 1, 2010.^[5] It is the fourth original 3D platformer in the Mario series, after Super Mario 64, Super Mario Sunshine, and Super Mario Galaxy.
The game retells the story established in Super Mario Galaxy, in which the protagonist Mario pursues the evil Bowser into outer space, who has captured Princess Peach and taken control of the universe using Power Stars. Mario's subsequent adventures revolve around traveling to various galaxies to recover the Power Stars in order to travel to the center of the universe and rescue the princess.
The game was originally planned as a simple iteration of Super Mario Galaxy with few modifications and a projected development time of a year (this version would be called More Super Mario Galaxy). It was later decided that the game was to be developed as a fleshed-out sequel when the development staff continued to build upon the game with dozens of new ideas, and so development time expanded to two and a half years. Among the additions are dynamic environments, new power-ups, and, most notably, the ability to ride Yoshi.
Upon its release, Super Mario Galaxy 2 was met with critical acclaim, and it has been listed as one of the highest-rated video games ever by aggregation sites such as Metacritic and GameRankings. The game is one of the best-selling games on the Wii with 5.1 million copies sold worldwide.[6
