Lego has done two things to destroy the fun. Firstly, they produce specialized pieces in almost every pack. Pieces that are unique to that pack, making it impossible for someone to build that creation with pieces from other packs. Secondly they have tied the packs to other franchises and jacked up the prices. Worst of all is when they turned it all on its head by creating their own "franchise" and jacked up the price. Yes, created their own cartoons and market and then charged a premium price for the Lego linked to it. I am talking about Ninjago. Shame Lego, shame.
