I really like this game. It starts off a little slow, but once you've trained a little bit it becomes a lot of fun. There are tons of characters to play with and unlock in story mode. I didn't like how they tweak the story here and there, but other than that it is a great game. Many of the battles are very similar to how they play out on the TV show. I normally send games back as soon as I beat them but I can't put this one down. I am still playing it well after completing the story mode section of the game.
This is most definitely one of the best games that I've ever played on the ps3 making a close second to uncharted 2 this game is very fun the story mode is very enjoyable even for non-naruto fans and the graphics are amazing the story mode is very dry at times and the american voice acting isnt too thrilling i recommend using the japanese voiceovers
Now moving on to the free battle, by far the highlight of the game, its very fun, even by yourself. and unfortunately the online play is very lacking and often glitches up but other than that it is a great game.
I recommend renting it before you decide to buy it.
