The game of choice in the Harry Potter universe is Quidditch. The first time we see a Quidditch game is in The Chamber of Secrets where Gryffindor plays Slytherin. In October 2010, LEGO released the Quidditch Match (4737) to recreate the scene. This set contains 153 pieces and retails for $19.99 which comes out to $0.13/piece.
