Naruto: Ultimate Ninja 3 adds a whole lot of customization to the game. While previous versions had some, there was just too much of a hassle involved to actually attempt it, and many, if not all, of those issues seemed to be resolved here.
There are two ways to customize your characters and their moves, the first being the way you actually assign a move to a character. As you play though Ultimate Path, you will be able to buy, or unlock, various items. Giving these items to characters allows them to use their various Jutsus.
The other ability you have is to assign the type of input you use on your major attacks. In previous versions, as well as similar games like Dragon Ball Z: Budokai, moves require you to tap a series of buttons, or spin the sticks. Here, if you are better at spinning analog sticks, then you can assign that input type to your Jutsus, or if you have quick enough reflexes to make the button-tapping work, then you can set them to that. I found this to be a nice piece of customization since I tend to be better at the stick-spinning.
There was also an odd mechanics issue I found in the Ultimate Ninja open world. The village is littered with buildings you can go into; unfortunately the button to enter the building is the same one you use to jump. I can't tell you how many times I was trying to jump onto or over a building and ended up going inside it. While this is only a minor annoyance, it was frequent.
With its large roster and generally fun gameplay, Naruto: Ultimate Ninja 3 is one of the best fighting games to hold the license and I would definitely recommend it to any orange-jumpsuit fan out there, but like I said, other fighting gamers might want to rent first since the gameplay style of this series isn't exactly the same as most other games.
