My son wanted these because of the latest craze at school. At first I thought they were too expensive for such a small toy but after purchasing the first 2 sets (you need six bakugans to play the game) I think they are incredably well made and some of the Bakugan are incredably complex, everyone was impressed at how much mechanical detail goes into making one of these Bakugan. My son, daughter, father, sister,mother, husband and myself have all had a go, and yes we do quarrel over who is going to have the better looking ones.
