This game REALLY was dissappointing. Rent it first!!!!
The Good: Nice graphics, and a good storyline.
The Bad: Too easy, too short, only went to Cell saga, broken gameplay, barely any characters.
This game was just plain BAD! There was barely any characters, and it had a copied, broken gameplay. There's also the fact that it only went to the Cell saga! I mean, It's on the PS3. It had enough space to put in WAY more work, characters, gameplay, and length of the actual game. But they just threw it together without any work whatsoever! It could have been brilliant, spectacular, but it just wasn't. Also, in the middle of a battle... Just when you're about to win that level... BAM! That same cutscene you've seen a million times before, it happens again. Then your opponents health is sky rocketing again, and you lose. I'm referring to the extremely annoying "Drama Pieces" It would be okay you could skip them by pressing a button or something, but you can't. You have to watch that same bullcrap again. Over and over again. Constantly. And why did they only go to the Cell Saga? I'll never know. They could have done GT, and the Majin Buu saga, AND the Dragon Ball saga. But they were pretty lazy, and couldn't be bothered to go past the Cell saga! Same with there being barely any moves.
Bottom line: Either rent it, or just don't buy it. DON'T waste your money, make sure you like it first. It really was a huge dissappointment. So don't expect much. If anything at all.
