Story: That depends on your choice. If you like tenkaichi 3 story (short) or raging blast (long). The length is ok but suffered due to less characters. There is also nothing to do. It looks pretty but the only choices are story fights, dragon ball hunting, tournament, and random battle (which are only 2 different characters). The worlds are empty.
Graphics: Beautiful. Enough said
Gameplay: way too simple. My fights usually last 20 seconds which is sad. You can easily win a fight against the computer. People are a bit harder but not by much since you can spam. It's pretty much a guessing game. You well get bored because everyone has the same animations for their pursuit chains. It gets repetitive. Boss fights need a bit work but it is ok.
Sound: Music is great but the dialogue suffers. Why? Laziness. If you listen carefully you can hear the original cast and the kai cast on the same character. That's just laziness.
Misc: The only good thing is hero mode and that isn't saying much. Making your hero (only male saiyans) is very limited and you can only make 3 different types (1 of each). The story is limited and seemed rushed. There is no interaction with other characters. I wouldn't mind having my saiyan interacting with Goku or Vegeta.
Overall this game needs work. The sequel needs to improved. If your a hardcore fan then its a rental at most. Otherwise skip it
