Great Shippuden adaptation!
It makes you feel like playing the original story, and on top of that, it also includes some scenes that were not in the tv adaptation, which make the game even more exciting.
It has even more than what a normal fighting game would have, not only fights, but also mixing it up with some exploring, finding items, teaming up with many of the characters from the series.
Who ever said that this game is "fair" is completely wrong. Don't expect to have everything unlocked at the beggining, because actually the best part of the game is the fact that you can explore and unlock things/characters while you play it.
