When I first saw Skylanders figures in store, I thought "Those are neat. NEVER going to catch on though, I'll pick some up on clearance."
I was way off obviously.
As I watched my nephew tear open figure after figure during Christmas, I wondered why no one has copied that format, game then all these accessory add ons. Pokemon seems like an obvious choice, but I'd be in trouble if they ever did Marvel or DC that way.
