Ok, I am not a Naruto fan, but it wasn't that bad.
I thought it was sort of a copy of the Dragon Ball Z: Budokai games. I like budokai, and I would say that it is way better than Clash of Ninja. The budokai games have more variety in everything, and they are more original. The graphics are ok. I didn't really play the game that much only twice, it was kind of annoying if you are a true budokai fan. If you like Naruto, you'll probably get this game no matter what, but I'd say that you shouldn't.
