The reason this entry cannot be number one is it was born to die. Created with the sole instruction of "get the money, get out, no witnesses," Dragon Ball Z: For Kinect is a product of both laziness and incompetence; the Star Wars Battlefront 2 of its kind. Namco-Bandai believed (much like their predecessors did with UB22) that they could take assets from an older game, Dragon Ball Z: Ultimate Tenkaichi, combine it with a rebarbative first-person view and Kinect-based motion controls, and then sell it for $60. They were correct.
This is a game entirely at odds with itself. You can unlock new fighters, but they all play exactly the same way. Even if they didn't, you're in first-person mode more often than not so you can't see the action even if you wanted to. It focuses on slow, deliberate movement largely due to the incompetence of the Kinect, yet everything seems to respond when it god damn well feels like it. The difficulty in this game does not lie with anything relating to the gameplay, but instead lives and dies entirely based on the hardware that it needs to function. You'll fight tooth and nail with the Kinect over every minutia, a never-ending dialogue that leaves you with a realization that you've wasted so much time and money on Dragon Ball Z: For Kinect. Once the fun of the Kinect semi-registering your kamehameha pose wears off, you can essentially consider the game completed because all that you'll have left is a very boring, extremely interpretive Dragon Ball Z themed choreography DVD.
It shares identical graphics and a shot-for-shot copy-paste of the story mode from Ultimate Tenkaichi, so you might be thinking that if you played that game you have absolutely no reason to pick this up. That's close, but the reality is no one has any reason to pick this up. You can indite the entirety of the Kinect's existence off the back of this game alone. This is the game equivalent of a film made by The Asylum. It was designed to take as much money from people as possible using a franchise they liked until they caught on as to how awful the product actually was.
