Not a great game but still oddly good
The graphics are quite good with all the characters being recognisable. The music is also fairly good.
The Gameplay is hard to describe, there's no story but instead a series of missions that roughly link if you've seen the show otherwise you'll have little idea what is going on. The Jutsu system is pretty brilliant and imaginative which has you performing tasks like blowing into the microphone, forming hand signs and hitting Chakra points. There are no other single player modes making the large amount of characters useless. The game does have a large amount of characters however the US version has even more such as Kisame and the sound 4, however the fact that you can equip any Jutsu to any character ultimately means that all the characters are pretty much the same, this was the most disappointing thing about the game.
To sum up the game has nice visuals and a good character selection however choosing your Jutsus really spoiled the large amount of characters, the campaign mode is nothing short of a mess. That said a hardcore gamer or Naruto fan may find a couple of hours of fun in this but ultimately it was disappointing.
