Super Mario Galaxy 2 was announced at E32009, a trailer was shown, since then, there was not too many information available for the game. Super Mario Galaxy was originally supposed to be titled “Super Mario 128” and was also supposed to be a near-launch title for GameCube. Later, Nintendo decided to push Super Mario 128 aside, and focus more on a traditional, yet innovative Super Mario game with Super Mario Sunshine. Super Mario 128 was revealed during a trade show called SpaceWorld 2000 – in which is the same show that Zelda for the first time was shown to the public showing off the power of the GameCube, and like Super Mario Galaxy, the game became “Zelda: Wind Waker” – Super Mario 128 was supposed to exemplify the power of the GameCube the same way the original Zelda footage was to show the power of GameCube.
Without further ado, the second trailer of Super Mario Galaxy 2 for the Wii:
I don’t think you need to buy Super Mario Galaxy in order to follow the story, because the creator of Mario said that the game is 95–99% new features, which means they place more emphasis on gameplay, than story, and plot. Nintendo of America President and CEO Reggie Fils-Aimé said that the game will be more challenging than the original Galaxy. The game features these comet metals in which you can collect alongside coins like a typical Mario game, these comet metals are designed to be collected to allow for unlockable stages with difficult challenges. Super Mario Galaxy 2 releases on May 23, 2010.
