Super Mario Galaxy 2

Super Mario Galaxy 2 is the sequel to Super Mario Galaxy for the Wii. It is the fourth game in the 3-D series. The sequel contains many elements from its predecessor, with objects such as Launch Stars and items (like the Bee Mushroom) returning, and the elements of gravity remain the same. However, the game introduces new elements such as Yoshi, new power-ups and the use of a guide within the game for beginner players. All releases of the game except for the American version include a beginner's DVD. For North America, help for beginners is found on the official website, as well as in the Nintendo Channel.

Story
Every one hundred years, shining stardust falls on Mushroom Kingdom. On this particular day, stardust falls on Mushroom Kingdom. Residents of Mushroom Kingdom come out and enjoy the stardust being thrown everywhere.

Princess Peach invites Mario to share some cake while watching the shooting stars. On his way to Peach's Castle, Mario finds a lost Baby Luma. The Luma seems to like Mario, and jumps into his hat. At Toad Town, Mario discovers a large, planet-sized Bowser attacking the castle. Bowser explains that he used the power of the Power Stars to become giant. He kidnaps Peach and takes her away, hoping for her to witness his creation of his new universe and bake him some cake. Mario heads to the castle where he finds two Lumas. After seeing Baby Luma with Mario, they offer to aid Mario in his search for Power Stars. One of the Lumas transforms into a Launch Star which sends Mario to Sky Station Galaxy. After getting one Power Star, Mario flies to Starship Mario, where he meets Lubba and the other characters.

In his adventure, Mario must collect as many Power Stars as he can, so Starship Mario can proceed through 6 worlds and reach Bowser's main fortress.

After going through several galaxies and fighting off new enemies and old (such as Whomp King and Bugaboom, fighting Bowser twice and eventually blowing up Bowser Jr.'s machine to send him flying into space) Mario fights Bowser for the third time in his gigantic fortress. After Mario defeats him, Bowser falls into a void below. Just when Mario is about to get the last Grand Star, Bowser suddenly returns and eats it, making himself huge again. The characters then fly through a vortex in which Mario must pound meteors toward Bowser as he tries to attack him. Mario defeats him and rescues Princess Peach and the final Grand Star.

After defeating Bowser for the final time, Mario gets the final Grand Star, along with Princess Peach. Upon returning to Starship Mario, a blue comet appears and transforms, revealing the Comet Observatory. Rosalina then appears, happy to see that the Luma was safe. It's also revealed that Lubba and Rosalina have met each other before.

When the Baby Luma heads back to his home, he takes Mario's hat as a souvenir, which takes Mario by surprise. Afterward, Rosalina and the Baby Luma return to the Comet Observatory, and the ship flies off.

With the Comet Observatory gone, Lubba mentions to Mario and Peach that it's time for them to return to their own home. The credits begin to roll after this. During the credits, Bowser will appear in a tiny form near Peach's Castle. After this, World S will be revealed.

If the player collects the first 120 Power Stars and battles Bowser one more time in his fortress, an extra scene is shown after the end credits, revealing Rosalina and her Lumas. She plans on telling the Lumas a story about the Green Stars. And with that, a new feature is unlocked in which all the galaxies will be visited by green Prankster Comets. From there, the player must hunt down all the Green Stars. Additionally, players can now have Rosalina as their file icons.

If the player successfully finds all the Green Stars (adding up to 240 Power Stars), the Grandmaster Galaxy will be opened in World S. Additionally, if the player gets that galaxy's Comet Medal and gives Banktoad 9999 Star Bits, a Prankster Comet will appear at the Grandmaster Galaxy, allowing for the final star to be collected by completing the final, difficult level, The Perfect Run.

If the player succeeds with the very last star, Rosalina will congratulate him/her, and will appear back at the Starship Mario. The player will also receive a message that will appear on the Wii Message Board.

On a side note, when the game is 100% complete, the save file will display a counter, representing how many times the player lost a life (just like in the predecessor). The file will also read 'Master of Galaxies' and have a special crown instead of a gold or silver crown.

Gameplay Elements
Gameplay is similar to Super Mario Galaxy, with a focus on platforming based on and around 3-D planets of varying sizes and with many different types of surfaces. Power-ups, such as the Bee Mushroom, Boo Mushroom, Spring Mushroom, and Fire Flower make a return, along with new ones such as the Rock Mushroom and the Cloud Flower, as well as various enemies and Airships. Launch Stars reappear for interplanetary navigation, along with a Luma and Mario's spin action. Additionally, the concept of "Dark Matter" appears as the medium of which Cosmic Clones are composed, and as a portal through which Airships emerge from. 2-D stages featured in Super Mario Galaxy are also included in Super Mario Galaxy 2, introducing many new features. The game has only 3 file slots to use, unlike the 6 files in the preceding game.

One of the more notable additions in Super Mario Galaxy 2 is the inclusion of Yoshi. If Mario were to discover a Yoshi egg, he would merely crack it to release and use Yoshi. Yoshi will change colors when eating either a Dash Pepper, Blimp Berry or Bulb Berry; a Dash Yoshi darts at rapid speeds, a Blimp Yoshi inflates and floats upwards, and a Bulb Yoshi lights up and shows hidden paths for a certain amount of time, respectively. When utilizing Yoshi, the player's Wii Remote cursor turns into a red sphere that detects targets for Yoshi's tongue. Using the cursor allows Yoshi to swallow enemies and swing from special flowers.

Elements from older games are also included in the new game. These elements include a remix of Super Mario Bros.'s overworld theme (which is originally heard in Toy Time Galaxy from the predecessor, Super Mario Galaxy), a galaxy that is reminiscent to Giant Land from Super Mario Bros. 3, a remix of the second overworld theme from Super Mario World, the checkpoint flag from New Super Mario Bros. Wii, and a remix of the main theme and slide theme from Super Mario 64. Red and blue platforms from Super Mario Sunshine will also be available, though they change sides when Mario spins in mid-air.

It is noteworthy to mention that Super Mario Galaxy 2 features a singular hub, different from any Mario 3-D game. For traveling between different galaxies Mario will use a planet shaped like his head, Starship Mario. Starship Mario can still be explored, much like the Comet Observatory, although it is smaller. The game has a total of 242 stars to collect, including 120 Power Stars, 120 Green Stars and an extra 2 Power Stars in Grandmaster Galaxy.

Multiplayer from the original Super Mario Galaxy reappears, but instead of being another star cursor, the second player is a Co-Star Luma. The second player in Super Mario Galaxy 2 can stun enemies and pick up Star Bits like in Super Mario Galaxy, but now it can pick up coins (including Purple Coins) and mushrooms, defeat enemies by spinning, stop the Star Ball (while player 1 is riding on it), activate checkpoints, and flip switches.

Super Mario Galaxy 2 features ways to help players during gameplay similar to the Super Guide mode seen in New Super Mario Bros. Wii. The player may request to the Tip Network, which it is a short demonstration of Mario taking some actions to progress on certain level. Another way the game offers is the Cosmic Guide mode. If the player finds a very difficult obstacle on his or her way, an entity known as the Cosmic Spirit will ask Mario if he needs some help. Activating this mode, Mario will pass automatically through the level to find the Star. The player may stop this mode by pressing the D-pad, though once the player has chosen this mode, he/she will finish a level by getting a Bronze Star instead of one gold. The player must play through the level without the Cosmic Guide in order to gain a gold Star.

In addition to that, unlike in Super Mario Galaxy, the player can now switch between playing as Mario or playing as Luigi in certain levels. If the player clears Bowser's Galaxy Generator, Luigi can be played as in any level.

Development
The development of Super Mario Galaxy 2 started as soon as the first Super Mario Galaxy was released. Many of the ideas were based on those shown in the first game, which for example included moving or adding new stars in the levels. The project was early called  Super Mario Galaxy 1.5. The development of the new version of the game lasted a year; however, Miyamoto realized that the new game overflowed with new elements and ideas, therefore the team decided to create a real Super Mario Galaxy sequel rather than a new version of the original installment. The development of the sequel then lasted two and half years.

The game was revealed in 2009's Electronic Entertainment Expo along with New Super Mario Bros. Wii. Although the game was worked very well along development, it was held back to 2010 due to the release of New Super Mario Bros. Wii in November 2009. According to Shigeru Miyamoto, 90% of the features in this game are new, whereas the remaining 10% were already introduced or featured in the original Super Mario Galaxy. Shigeru Miyamoto noted, "Really what we ended up with is more than 90% of what you'll see in Galaxy 2 is brand new. I'd say closer to 95, maybe even 99%. One of the new things was the inclusion of Yoshi, and also the use of the drill to open up and drill through stages." On the other hand, Miyamoto stated in an interview that he liked to go with as little story as possible for Super Mario Galaxy 2.

CEO of Nintendo America Reggie Fils-Aime stated that Super Mario Galaxy 2 would be more challenging regarding its predecessor. It was hinted that the new game would implement a tool-assisted guide, similar to the Super Guide from New Super Mario Bros Wii which was eventually confirmed, though the tool worked differently. Beginner players could use the Cosmic Guide mode (activated when encountering the Cosmic Spirit) or the Tip Network to learn moves and hints during gameplay. Japanese, European and Australian boxes came with a special DVD to help players to know basic and expert techniques of the game.

Reception
Super Mario Galaxy 2 has received extremely positive reviews. EDGE magazine has given the game a perfect score of 10 out of 10, being the third Mario game so far to receive such rating (the others were Super Mario 64 and Super Mario Galaxy). Official Nintendo Magazine grants it a 97%, while Game Informer has given the game 9.25 out of 10. IGN and Gamespot granted the game a perfect 10/10, as well as GamesRadar. Gametrailes has given a 9.7 from 10, while Famitsu a 37 out of 40. GamePro gave four and half stars, X-Play gave it a perfect five out of five stars, and 1UP.com an "A" rating.

References to Other Games

 * Super Mario Bros.: Supermassive Galaxy's music, which is itself a remix of Toy Time Galaxy's music from the first game, originated from this game's overworld music. Other music from this game returned from Super Mario Galaxy as well.
 * Super Mario Bros. 3: Supermassive Galaxy is similar to Giant Land from this game, as the two are of massive size and feature giant versions of common items and enemies.
 * Super Mario World: Yoshi, who first appeared in this game, is playable in Super Mario Galaxy 2, and the percussion sounds heard when riding on Yoshi are re-used again. Additionally, this game's athletic theme returns as Hightail Falls Galaxy's music, and the Ghost House theme returns as Haunty Halls Galaxy's music. Also, the sound effect that is heard when a P-Switch's effect is about to run out is used in the bonus areas of Super Mario Galaxy 2, and the sound effect heard when passing through a door in this game is used when opening a door in Boo Moon Galaxy.
 * Super Mario 64: The music from The Princess's Secret Slide from this game (and its remake) is used for Tall Trunk Galaxy and Rolling Coaster Galaxy. Also, Throwback Galaxy from Super Mario Galaxy 2 is a replica of Whomp's Fortress, and its boss, the Whomp King, is fought there. Both games start with Peach sending a letter to Mario involving cake. Additionally, the "Inside the Castle Walls" theme can be heard when rescuing Peach and the final Grand Star in Super Mario Galaxy 2.
 * Super Mario Sunshine: Starshine Beach Galaxy is based on some elements from this game. Twisty Trials Galaxy is a replica of a level in Ricco Harbor. The red and blue flipping platforms return, although they work differently.
 * Super Mario Galaxy: Many planets and bosses from this game return, and parts of Dino Piranha's egg are orbiting Peewee Piranha's planet. A few bosses are based on bosses from the prequel, like Peewee Piranha to Dino Piranha and Digga-Leg to Megaleg. Also, the last boss before Bowser's final battle is a fiery version of a boss fought before in the game, like in Super Mario Galaxy. Most of this game's bosses are fought in Super Mario Galaxy 2, and many elements from this game return. Both games start with the Star Festival.
 * New Super Mario Bros. Wii: The Midway Flag returns from this game, and the Cosmic Guide and Tip Network are based on the Super Guide and Hint Movies from this game, respectively. Also, the world maps are based on the one from this game. In both games, Bowser is giant, and the final battle is divided in two different parts, the later having a bigger Bowser. The model for the Koopalings' cake reappears in Super Mario Galaxy 2's credits. Additionally, when players collect all the coins in a certain time limit that were accessed by a switch in Super Mario Galaxy 2, the audience claps in the same fashion they did in this game.
