Disney's skylanders

This article was about Disney's new up and coming video game, Disney Infinity. A thing I learned from this article is that the game has the same concept of Skylanders, with the physical figures that you put on a platform which brings them into the game. Another Thing I learned from the article is that each character has its own game attached to it called a "Playset" each playset is set in the character's world. I also learned that the game features a mode called "Toybox" where characters can build worlds and play with their friends. A thing I like about this article is that Disney is finally making a (Some what) original game, not just a licensed game set around a single movie.  Another thing I like about the article is that it explains that Disney is trying to compete with Skylanders and Minecraft with this games release. A question I have about the article is Does each "Playset" have to be downloaded off the internet before playing?
