Summary: First off, let me say the game is great. Especially the story. The story takes place years after the events of Partners in Time where Fawful gets his revenge plan mentioned in Partners in Time. By giving Bowser a special mushroom, Bowser goes insane and starts sucking up everything, including the Mario Bros. Later, after forming a secret alliance, they find Fawful using the power of a dark star, (opposite of The Beanbean Star) and turn into dark Fawful.
Summary: If you like other Mario games, this is for you -- great game play with excellent graphics and plenty of characters, levels, etc. It's what you expect from the Mario series. Good for all ages. Everyone in my family likes it.
