Looking to get the kids Disney Infinity Starter pack for Xmas, but little confused....  3.0 has just been released and the 1.0/2.0 characters are usable etc.... thats fine, but playsets are mentioned such as Star Wars, Inside Out etc.... what are these playsets, are they seperate  games (Like Skylander Giants, Spyros Adventures etc) , or are they all included on a single game disc or what.....  ? :)

TIA
