The main gist of this game is explained in the title of the game, but it's how you get there that is kind of goofy. After you pick whether you want to be a little boy or girl, you then start the game on an island, where you talk to the folks, gather chickens, sheep, carrots, etc to feed your dragon.
Training your dragon to level up is done in a little cave, and it's step by step combo trainings against a AI that rarely fights back. More get unlocked as you win more tournaments. You also get alot of experience for playing the mini-games, such as ice sculpting, memory torch, etc. They are all relatively easy, and with practice should have no problem acing them. The mini games actually give you more experience in the end that the dragon training, which is kind of weird.
The meat and potatoes, the fights, are clunky. The battle system is a very weak one, and it's difficult to move around with ease. With that being said, once you have it down pat, and figured out, you should be able to ace these fights with ease. A combo of hard knocks and fire, rinse and repeat, and you have a win in the bank.
Another key to the game is the customization of the dragons, where when you level them up, you unlock more features to add to their appearance, and color palate. Kids would have a blast "creating" their own dragon.
And that's pretty much the game.
For graphics, I'd give this game a 7. For gameplay, I'd give it a 6 For the battle system, I'd give it a 3
I'd recommend it for kids that enjoyed the movie, and for the general gameplay that involves the harvesting to heal the dragon. Should keep them involved for awhile.
