I can see that the bedroom of our son will eventually be festooned with characters from this series, as it is an appealing gimmick to have the ability to have a physical avatar of the character being played to act as a companion in the room, but with a cynical eye, I believe that it is a marketing gimmick that will cost more than it will return in enhanced play.
Brace yourself, as a parent, for the inevitable whinge about needing another of the 100+ Skylanders available. Calculate the cost of something that eventually will go the way of the Hot Wheels racing track that always falls apart and brace yourselves for not having the price of a pint (or three) at the pub due to it having been converted into a small piece of garish plastic.
Yaaay. Parenthood, more than a job, it's an experience in avoiding bankruptcy through video games.
