Super Mario Galaxy 2 [Wii - Beta / Unused Stuff]

Super Mario Galaxy 2​ is a platform developed by Nintendo EAD and released for the Wii in 2010. As we can read on Wikipedia, shortly after the first 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.

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. Super Mario Galaxy 2 was first shown at E3 2009, with a beta version that was similar to the final one, but still had some interesting differences, as noted by users at the Super Mario Wiki:

In the debut trailer from E3 2009, there were several changes before the game’s release date.

A planet shaped like Mario’s head could be seen. This planet is an early version of the Starship Mario.

In Cosmic Cove Galaxy, the switch which freezes the water into ice is placed on a wooden buoy-thing, similar to the place where Penguru is standing. In the final version, the switch is found on a tower.

The starting planet in Boo Moon Galaxy originally was going to have a different type of terrain and coloration that did not resemble the interior of a haunted mansion.

A giant Silver Chomp seemed to appear as a boss, possibly in the beta Battle Belt Galaxy.

Comet Medals were designed differently, as the comet’s star had no eyes.

Mario is seen sliding on a stone planet similar to Tall Trunk Galaxy’s Trunk Slide Planet is present. This game doesn’t exist in the final version.

On the E3 trailer, Sky Station Galaxy’s Soundtrack had an extra part (that sounded like a part from Gusty Garden Galaxy) that didn’t make it to the final.

In a beta version of the Flower Planet in the Supermassive Galaxy it was shown that Goombas appeared. In the final version, they don’t appear. Plus there were different flowers when Mario walks on the planet and the planet was made of dirt instead of grass.

Blue Grass Galaxy is a name for a possible scrapped beta development level of Super Mario Galaxy 2. Proof of this galaxy may exist in the E3 2009 Announcement Trailer of Super Mario Galaxy 2. A screenshot showing an unknown platform with Mario jumping on three Twirlips in a row also shows a planet in which resembles none of any of the planets and galaxies in the final release of
Galaxy 2.

There are two songs that did not make it into the game. Galaxy song 19 and “SMG2_galaxy08_strm” Galaxy song 19 is rumored to be the main theme for Blue Grass Galaxy. SMG2_galaxy08_strm was scrapped but did not become orchestrated.

Finally, although they are not found in the final game, Ice Mario and Flying Mario from the prequel can be playable via hacking. Despite the fact that they were apparently decided to be scrapped early, updated versions of their themes were found as well. Some test levels and models have been found hidden in the code of the final game, but you can’t get to them, since they lack a “UseResource.arc” the game will crash when loading them.
