It is a fine game for kids who are into Bakugan, but even after the patch, there's an over reliance on buffs and debuffs thatkind of just boil down every strategy to simply debuffing the enemy and attacking with a particluarly strong attack. There is also little incentive to collect more Bakugan as you progress through the game, and Leonidas was a disappointment.
