It’s totally reminiscent of jumping around the Leaf Village in UN3, but now it’s way bigger and Naruto has way smoother and more interesting movement. That being said, the hub world is fun to explore. The side missions at least have you meet characters within the hub world to unlock them and later to complete them, but with the main ones you’re just teleported into story world, I guess. The way that’s handled is not amazing, you have to pick the missions from a menu. You control Naruto and explore the Hidden Leaf Village between missions. So, the story mode basically covers all of original Naruto, excluding the Zabuza arc.
