Hmm, and reading the pack's features is like reading the features of some crappy DVD.
* New Level Expierince
* New Villians
* New Friends
* New Tilesets
* Meet Mario And The Lost Vikings
* Big Levels
* And Some Crazy Bosses

The only thing missing is *Interactive menus
EDIT- However, Big Levels would be something put on a fancy DVD feature list, let's just hpe they have good/fun content.
