Yes thats right. This game RULES. You are Mario, and at the beginning you have to save the princess (again).  After that, a giant sword with a face crashes into bowsers castle, flinging Mario, Bowser, and the Princess all in different directions AND destroying the star road that connects the mushroom land to bowsers keep. So you gotta go find the 7 star pieces to the star road, and find out what that sword is (just play the game, lol) Bowser and the Princess joins your team later along with a few new friends: Mallow, and a doll that comes to life named Geno.  As you play you come up with new spells, weapons, and sometimes you run into little games and puzzles.
