About Ninja Storm 3, there's an "ultimate" version out there, Full Burst, which has additional content. MSRP is $39.99, though it does have quite a bit more content:
* Additional Chapter - Finally free of Kabuto's control, Itachi intends to crack the Reanimation forbidden technique. Will an unprecedented Uchiha alliance with Sasuke be enough to handle it?
* New Playable Character - Kabuto reaches the almighty Sage mode and is now playable in versus mode. Unleash his power and defeat your opponents both offline and online.
* Director's Cut - Discover completely revamped Storm 3 cinematics and experience the epic conflict consuming the entire ninja world more intensely than ever.
* 100 New Missions - Embark on a whole new series of missions, many with their own uniquely challenging objectives.
* 38 Additional Costumes - Outfit characters in a selection of 38 costumes from the NARUTO SHIPPUDEN Ultimate Ninja STORM 3 DLC packs.
Since it's $40 on BB, it would be $32 after GCU discount, so $12 or so for the additional DLC assuming $19.19 for the cost after GCU discount. Without GCU discount, you're looking at $16 for the additional DLC.
