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, last employed in New Super Mario Bros. Wii. The music heard during the trailer is a remix of tunes found in the original.

Story
Nothing has been revealed currently, but an ice statue of Bowser appears as well as airships emerging from a warp. Mario is also seen fighting a robotic enemy resembling Megaleg, and later a giant one-eyed snowball/rock-like creature. A giant Chomp Head also appears to be chasing Mario at one point, and Bowser Jr. appears inside a giant robot's head, in which he seems to be controlling. .

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, will be making a return, along with 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 or Blimp Berry ; an orange-colored Yoshi darts at rapid speeds, while a cyan-colored Yoshi inflates and floats upwards, 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, such as red and blue platforms from Super Mario Sunshine will also be available, though they change sides when Mario spins.

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."

Super Mario Galaxy 2 has appeared in Nintendo's 2010 Media Summit and it is confirmed to make an appearance at E3 2010.
