Here is a review by someone who is not a die hard fan of DBZ.
Now on to the gameplay, the gameplay is actually quite good, not very, but quite, i enjoy those battles even though the get repetitive and boring after some time, but still with the large number of characters its really hard to get old, but unfortunately it does, thats about all i can say, i am not going to go into all the crappy camera which didn't disturb me much and the other stuff.
The graphics and animations are smooth, pretty and shinny. overall not much to say about those, sound effects and music are really appropriate in most battles and thats that.
about the multi-player, i haven't played it yet, but i have played with friends and might i say its a raging blast, and actually feels like the reason that game was made for
I don't really have any other remarks that game spot hasn't mentioned, overall the game is really fun, but gets boring quickly because of the lack of an actually story mode, and the battle mode gets old pretty quickly, so here is the math 10-2(for plot)-3(for getting old quick)+2(actually really fun with friends) so for me its a 7 with benefits.
