Pretty ordinary.

User Rating: 5.5 | Naruto: Clash of Ninja Revolution WII
-Good-
Easy to play
Somewhat balanced characters

-Bad-
Story mode on hard wasn't exactly challenging
Gets boring fast
Odd cast of characters.

Honestly i knew when i purchased it that it wouldn't be anything special, I can't say I've ever played an overly amazing Naruto game before so this was expected.
The game wasn't horrible but it's nothing I'd ever recommend to anyone, the fighting is pretty easy to get used to which is pretty good, so if you have a friend over and they haven't played the game before they can get used to it pretty fast.
It's fun, for about half an hour after that it gets really boring, the storyline was a chore i only did it to unlock characters.
The character roster was a bit weird, it was nice to see Itachi and Kisame on the list but i don't understand how they made the list yet Choji and Kiba didn't, hell even Tenten made the list and she is utterly useless on the show.
Sasuke and Kakashi have the option to use Sharingan, which is cool but i don't understand why Itachi doesn't, Itchai automatically starts the fight in Sharingan which to me is boring, it doesn't feel the same.

GRAPHICS: 6/10
For cell shaded graphics, they were pretty ordinary.
MUSIC: 7/10
Nothing amazing but it's nice to hear some familiar tunes from the anime.
CONTROLS: 9/10
HOWEVER i did NOT use the Wiimote for this game, i used the Gamecube controller, i have no idea how the Wiimote controls are but I'd imagine they would be pretty frustrating.
GAMEPLAY: 5/10
Basic in a good way, but gets boring very fast.
Single player is hardly challenging.
STORY: 9/10
Only because it's based off the anime.

If you're a die hard Naruto fan than it might be worth buying but other than that i wouldn't recommend it.
If you're looking for a good fighting game on the Wii stick to Brawl, it is A LOT more fun than this game.
