tl;dr I give this game a 6/10. If you are a huge fan of naruto be sure to pick it up, but if you're not you might want to buy something else instead.
First let's talk about the story and animation of the game. I really enjoyed the animation sequences and story mode, because it was like watching the anime but in cell-shaded 3D graphics. I have never watched the episodes that this game was based off of, and it made it that much more enjoyable because it caught me up to speed. That being said, the plot was a little too predictable for me and boring at times.
The gameplay of this game is OK. It feels kind of like a generic action game, but it has a chakra system and combo system which adds some depth. The kunai throwing does not seem to have any use. The time it takes to throw the kunai is time you could be using to close the gap on the opponent, and the damage the kunai does is so little that it's not even worth it. There are some issues with the combo system though, mainly that there is always going to be one combo that does the most damage and is usable in every situation. To avoid this they should have made multiple top-damage combos that are each used in different situations.
The UI and title screen could use some work, and I also had some issues getting the game to run at a proper frame rate. It had nothing to do with my hardware, but with the default settings that the game had. I would say that even though the game is good, the port of the game was very sloppy.
I give this game a 6/10. It is an above average game, but does not score higher than a 6 because of its bland combo system and port issues.
