It is a great game, if you're really into Naruto the anime series, or have played previous Naruto games. For people like me however, who were mildly interested in the game and never played any of the other Naruto games nor seen any of the show then its a bit confusing.
Confusing in that you really don't get a sense of who any of these other characters are. And confusing because it never really tells you how to initiate the stories.
I'd say this game is more of a fan service for those who have played previous Naruto Ultimate Ninja games before. Not bad, but not great.
