Good, but could be better.
There is no wifi multi-player.
It gets kind of pixely sometimes in a fight.
The characters some of them look a little strange.
Audio is good as long as you have headphones. Don't rely on the crappy DS speakers.
Great for fans of the show.
Great for collectors.
Fighting is a bit clunky.
Challenging plus lots of unlockables including Basil and Squalo for those who are familiar with those two.
I would wait another month or so for the second game if you were thinking of buying this. That is unless you have a dying will to play it or collect it then go right ahead.
