As good as it can get during its time.
The closest they could come to the show were the power struggles. Which were in itself kind of fun. No transformatins during mid game though. The gameplay was very stiff as well. I like the game though I felt it was decent. They also had a lot of the classic moves. Characters like Cell, Buu, Frieza, Vegeta are in it. Even Super Saiyen 4 Goku, and Vegito.
The color of the game was very bland and plain looking. I say that this game was just another stepping stone too get get to the perfect DBZ game.
