you dont get that much value because after doing one player mode once, it is boring to repeat itself. You play as mario and you find yourself once more, having to save princess peach. Bowser didnt capture her, the X nauts did. wrapped in mystery you must also save the earth, and open up a door. one at a time you collect crystal stars, each one possesing it's own power and individual strenght. you meet new people on the way and you use them for there powers, which come in handy every now and then. it's graphics arent perfect because everthing is PAPER, hence the term "'paper' mario".
