In addition to the range of classic LEGO bricks, kids can play with all-new features taken right from LEGO's Harry Potter line of toys. Design and build train tracks for Hogwarts Express to follow, or build furniture from LEGO bricks for the various rooms of a virtual Hogwarts Castle. LEGO Creator: Harry Potter also features a new 3-D character designer that allows kids to build their own mini-figure pupils. Then, click on the virtual Sorting Hat to place them in the appropriate houses of Hogwarts. How Hogwarts' pupils interact with each other will depend on what house they are from. For example, a virtual Slytherin mini-figure may react differently to a Gryffindor pupil than they do to a Ravenclaw student.
There are 12 optional challenges that add to the interactive play, including the option to download new LEGO bricks and virtual models from LEGO.com. The game also gives players the ability to create building instructions, so that they can build their own virtual models using real LEGO bricks.
