I disagree with the other reviews.
This game cannot be played properly in one hour, it's impossible. Furthermore, to unlock all the outfits you have to get a high score in each challenge.
I had no crashes either.
Graphics are good, and the game has role playing and activity elements. The storyline is fun and engaging, based on the CITV series, starting with introductions, ending with the Bratz going to London.
This review is based on watching my daughter playing. Children should be aged 6+ to get the most from it, although younger ones can still play with help from the parents.
She completed the whole game fully in about ten hours altogether, and still goes back and plays her favourite bits on occasion.
