The most expensive Lego sets in the world. Lego's revenues grew by a quarter in 2015 as consumers spent Â£3.7bn on construction sets and building bricks. But toys aren't just for playing.

Easily the biggest LEGO set ever created, the LEGO Star Wars X-Wing Starfighter is built using an insane amount of bricks -- 5,335,200, to be exact. It took 32 builders 17,336 manhours (about four months) to put it together at the LEGO Model Shop in the Czech Republic before being transported to Times Square for the undeniably grand unveiling.
