The graphics look like a game that was made 10 years ago. I do realize that it is a PS2 game, but so was Bratz: Forever Diamondz and the graphics on it were quite well done. In Girlz Really Rock, the characters aren't fluid at all. Their movements are stiff and limited. You can't even run through the water. I guess that would have taken too much animation. You can even make your character stand on a raccoon if you get it at the right spot. Things like that just shouldn't happen in a well done game.
The sounds are just as bad. For a game that you have to play music as a part of it, the music is very tinny sounding. Since the Bratz have their own music, of which 8 songs are available at itunes, you don't get any other licensed music in the game.
