Not only were the characters' sprites and level backgrounds for Ninja Council 4 made to fit the new storyline (which takes place about three years after the previous Naruto games), but the level of detail being added to the various images has also gone up, so not only do you get Naruto in his new black and orange jumpsuit, but he looks better than he did before. In fact, pretty much every character has gone up in detail, which is great for characters like Rock Lee and Might Guy who look very similar to begin with. The side-scrolling environments have also seen a bit of improvement with cleaner looking stages and backgrounds for you to run around in. Unfortunately, much like the previous games, the different locations (mostly the Leaf Village and the desert) start to look similar and can get repetitive quickly.
The game's audio seems to simply hit par with very little voiceovers (typically just grunts and calls made during combat) and cut scenes that merely use the static-images with text approach to convey the story. While the background music tends to have a distinct Naruto feel to it, it never really pulled me into the game and felt like it was super necessary for the overall presentation of Naruto Shippuden: Ninja Council 4.
