I was looking to see if Naruto Legacy happened to be on sale anywhere, because I didn't want to spend $80, for a copy, at Gamestop. I looked it up in the Xbox Game Store, and it's half off. You get all the Naruto Shippuden Ninja Storm games 1 - 4. Most, IF NOT, all DLC is included. I know there were a few characters, they didn't include in the DLC. I'm not too sure if it's a Gold Account Only sale, it didn't state that anywhere.
EDIT: It includes ALL DLC, just NOT the Goku costume.
