New World Map Replaces The Super Mario Galaxy Hub World

Throughout Mario's life, he has traveled all over different world, into other dimensions, and even into outer space. During his adventure Mario usually has a "hub world", or some other type of over-world map which is used to travel to and from different levels. Super Mario Galaxy 2 however, is going to try and change things up a bit.
Game Informer met with Shigeru Miyamoto to talk to him about Super Mario Galaxy 2, and how this new map will help the player travel in and out of different galaxies.

"We want players to focus on the joy of the action instead of getting to each game course," he said. "We wanted to make it as accessible as possible and as easy as possible for the players. Also, because we're going to incorporate a number of different stars, and conquering all the stars is going to be one of the most challenging missions for the player," Miyamoto added, "we want [players] to understand as easy as possible where they should go next and which places they should go back to in order to get access to the remaining stars."
It makes sense that Super Mario Galaxy 2 is going to try and streamline certain parts of its game, in order to allow a more casual feel. Miyamoto made sure to say however, that Super Mario Galaxy 2 will not be an easy game, the hardcore fans will still have a long adventure in front of them to collect all of the stars.
