I just read in the "Did you know?" section....
This aptly titled "Music Adventure Game" is more or less Aquanaut's Holiday crossed with a MTV Music Generator-style "Groove Editor" that gives the disc endless replay value. There are 12 huge areas to swim about as a dolphin, and they'll draw you in with some really beautiful visuals and fairly simple, yet unique gameplay. Think of a kinder, friendlier, new age-ier Ecco the Dolphin, and you've got a tiny idea of what's here. Did well enough in Japan to spawn a sequel, also on the PS, and since there's no breasts a-bouncing, big explosions, or blood galore, the chances of a PS2 sequel hitting the good ol' U.S. of A. are slimmer than Cameron Diaz under a steamroller.
i really want to know the name of the title as i`ve searched the net and cant find a thing. cheers.
