I agree that Disney's characters have more appeal because as soon as you see Elsa or Mickey in store, you have a cognitive connection to the character. You don't have to learn who they are at all. With Skylanders no one knows who the heck Voodude or EyeBrawl is, but they do have still have appeal. Kids love them (I mean come one, you can leave a flaming bag of poo behind you as Hot Dog). So while the characters may never have Disney status the games themselves are still very solid, well made games. I would definitely recommend them to anyone who enjoys playing a good game (and frustratingly challenging at harder difficulties).
