Super Mario Galaxy 2

Super Mario Galaxy 2 is the upcoming sequel to Super Mario Galaxy announced for the Wii, which will be released on May 23, 2010 in North America, and June 11, 2010 in Europe. The sequel uses many elements from its predecessor, such as Launch Stars, the Bee Suit and the elements of gravity, but also includes new elements such as Yoshi. The music heard during the trailer is a remix of tunes found in the original.

Story
Nothing has been revealed currently about the story of Super Mario Galaxy 2, but an ice statue of Bowser appears, hinting at his presence. Airships, which were featured prominently in several levels of the first game as Bowser and his son's main mode of transportation around the galaxy, also appear, emerging from some sort of black hole warp. Bowser Jr., as of the second trailer, has personally appeared inside a giant robot's head, apparently piloting it. . Mario is also seen fighting a robotic enemy resembling Bowser Jr.'s Megaleg robot from the first game.

In an interview, Shigeru Miyamoto stated that he would like to go with as little story as possible for Super Mario Galaxy 2.

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 landscapes. Power-ups, such as the Bee Suit, Boo Suit, Spring Suit, Fire Flower, and Ice Flower will be making a return, along with new ones like a special Rock Suit, as well as various enemies and Airships. Launch Stars will also reappear for interplanetary navigation, along with a Luma and Mario's spin action. Plus, there seems to be the returning "Dark Matter" that appears as the medium for Dark Marios and is seen 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.

Videos and images have shown Mario sliding down a ramp, swimming underwater, picking up and utilizing a drill, hitting switches that freeze or solidify water , hitting switches that briefly decelerate time and discolor the screen , and rolling a giant snowball. In some Purple Coin stages, Mario appears alongside many Dark Marios. There is also a galaxy of which some planets appear the forms of percussion instruments.

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 Glimmer Bulb Berry  ; an orange-colored Yoshi darts at rapid speeds, while a cyan-colored Yoshi inflates and floats upwards, or a yellow-colored Yoshi that 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, and the checkpoint flag from New Super Mario Bros. Wii. 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 will not feature a hub, like the original's Comet Observatory, for traveling between different galaxies, making it the first 3D Mario game to do so. Instead, Mario will travel through the universe on a planet shaped like his head, Starship Mario. It has also been noted that the game will have over 240 Power Stars to collect. , but it is unknown whether this means that there will be 240 unique stars, or that Mario and Luigi will each collect 120 stars like in Super Mario Galaxy.

Development
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 that "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."
