List of Super Mario Galaxy pre-release and unused content
Ads keep the MarioWiki independent and free :)
The official Prima Games Guide for Super Mario Galaxy was released in two editions: the Premiere Edition and the Collector's Edition. Among the features included in the Collector's Edition were six pages of concept art and development info from the game's developers.
Rosalina was intended to be related to Princess Peach. They have very similar appearances, reflecting this. Bonefin Galaxy was intended to be much darker, as was Deep Dark Galaxy. These were changed in the interest of playability. Guppy was originally a dolphin, and a friendly character. Some art of the Sea Slide and Beach Bowl Galaxies suggests that they were conceived as a single galaxy, with Beach Bowl's main planet in the center of Sea Slide's ring. A piece of concept art labeled only "fortress" is captioned as a piece that is very memorable to the SMG development team, since it was one of the earliest drawings of Galaxy. Ironically, the planet shown in the art is nowhere in the final game.
At one point, Yoshi was going to accompany Mario in his adventures in space, while Starship Mario was going to be the game's hub level instead of the Comet Observatory. Both did not appear until the sequel, although a planet shaped like Yoshi's head made a brief appearance in the Space Junk Galaxy.
Many things had different names in pre-release info:
Also, several things underwent graphical changes:
E3 2006 (May 10-12)
E3 2006 was the first event in which Nintendo publicly showed Super Mario Galaxy in anything akin to its final form, although it was quite different from the final game. In this prototype build, attendees were treated to a single-galaxy demo of the game, in which they were given ten minutes to find and collect a star. This build had many differences from the final game, although all the basic principles of the game existed in some form.
Star World was the demonstration galaxy created to show off Super Mario Galaxy for E3 2006. It was composed of many planets taken from other galaxies in the game. It was notably different from any galaxy in the final game in that it was composed of a "branching" path- choosing different routes on different planets could lead to different stars entirely. It was also notable for its heavy use of asteroids instead of unique planets. The final game ended up using these asteroids only twice, as moons in two galaxies.
This galaxy was inhabited by rabbits and the conjecturally named Cosmic Toads, who were distinguished from normal Toads by the star shaped spots on their caps. They gave players hints and explained the controls. Sometimes, the rabbits could change into Cosmic Toads. Their role was likely replaced by Lumas. They explained various aspects of the game to Mario.
Snifit Bot was notably different from the final game's Megaleg. It was not commanded by Bowser Jr, and not powered by a Star. The weak point started out blue, and became red once the outer protective layer was broken (in the final game, it starts out white, then turns pink). Also, the rotating light source is inside the glass dome on top of Snifit Bot, as opposed to on top of it. Megaleg has a small depression on the top of its head, which Snifit Bot did not. Snifit Bot had three coins near each of the two metal patches on its head, and two coins on each leg, making the battle somewhat easier for players. After it was hit for the first time, it guarded its weak point with four unbreakable walls, rather than eight breakable ones. When Snifit Bot is killed, its head smokes, which does not happen to Megaleg. Snifit Bot guarded a normal Star, as opposed to a Grand Star. It also has spikes on its legs, which are gone in the final game.
Tarantox was also different, though not nearly as much so as Snifit Bot. Attacking any of the fluid filled green sacs on it was enough to flip it over, while in the final game, only the large one on its bottom is sufficient. Once the red sacs on its belly have been destroyed one time each, the final versions Tarantox will regrow all of the green sacs. Not so for Star World's Tarantox. The red sacs on Star World's Tarantox also pulsate more, and with a higher pitched sound effect.
King Kaliente's battle was almost identical to his battle in the released game. The only difference observed is that the flaming projectiles he shot could be batted away with the star cursor. However, not many videos of King Kaliente were released.
All three bosses did not release Star Bits when attacked, since there were only 100 Star Bits in the whole galaxy. However, no attendee to the show ever collected all of them, so their purpose remains unknown (they could not be fired at enemies as they are in the final game).
It is notable that every planet in this galaxy would eventually make it into the final game (although some were modified heavily), with one exception. The planet players started on (not officially named, but called "HomePlanet" internally by the game) is totally absent from the final game, although its model data is still present.
The planet just before Megaleg/Snifit Bot's planet originally had a grassy (as opposed to metallic) design. A minor glitch in the released game causes the grassy version of this planet to appear if players stand on top of Megaleg and look at the metallic version. This is caused by an incorrectly set-up culling method. When the planet was redesigned, its low-poly model was not. The series of planets leading up to Tarantox is significantly more decayed than the same planets in the final game. The same is true of Captain Olimar's ship. The first planet from Good Egg Galaxy is shown in a much different form here. Additionally, the planet with rolling boulders and mud from Good Egg Galaxy appears here, but without the mud, or the puzzle that would accompany it in the final game.
Although called "Star World" by fans, this name is taken from the "Welcome to the Star World!" message that appeared when starting this galaxy. Based on the similar message used in the final game, it could just be a mistranslation of "galaxy".
The music that plays in this galaxy is known as "Egg Planet." It is the theme of Good Egg Galaxy in the final game.
When Mario falls into a black hole, he has an oval like line.
Although no playable version of Super Mario Galaxy was shown at Game Developer's Conference 2007, a trailer was released, showing a much more complete version of Galaxy.
Since E3 was downsized to the E3 Media and Business Summit in 2007, less Galaxy info was released than in 2006. The first Galaxy related content was a press conference video, which was very close to the final game.
Later on, attendees were allowed to play a demo of the game, from which they had access to Good Egg Galaxy, Honeyhive Galaxy, and Space Junk Galaxy. The press conference video above is not from this demo, but from a very slightly earlier build of the game. Some videos taken by attendees reveal differences from the released game.
A demo of Galaxy was featured at Games Conference 2007. It is believed to be the same as the demo from E3 2007.
E for All
In all versions of the guide, readers are advised to look for a "unicorn-like horn" on the floor of the Bonefin Galaxy's main planet, since there is a red shell near it. The guide even shows a picture of the aforementioned. However, it is totally absent from the final game, suggesting that some modifications were made to the game even after it was given to the guide's writers.
HomePlanet, from Star World, still exists in the game's code. The Star World itself has not been discovered, and is probably no longer accessible.
Some unused models were found in the game . These include the following:
The low-polygon model for the house in Ghostly Galaxy has two chimneys that the high-polygon model lacks.
