A great result of the Skylander game

Third Skylanders game, and my son is still hooked.
The advantage is that the characters of the first two games running perfectly with this game one.
The disadvantage is that it is absolutely necessary to buy the package with the new base, as this game does not work with the old base.
For cons, the good idea is that this base it is connected by USB to the console, so more to excessive battery consumption!
