I got a Disney Infinity starter pack for my niece for Christmas.It comes with the game and several characters.However there is mention of different playsets.Evidently just because you have the action figure doesnt mean you have the playset.So what exactly is a playset and what does it look like? Is it a physical item or is it dlc? What do I need one for? The Disney site only shows action figures.The game manual doesnt explain anything.Heeeelllppp!!!
