I was about to answer with right I know, how comes my kids have almost zero interest in it. I used to play entire afternoons with it, especially the Technic kind.
neither of my kids have any interest in lego. not for lack of trying, they have several 10's of thousands of bricks, and enjoy the movies. I think it might be because they have zero interest in the licensed properties they promote.
I started lego in the mid 70s with my brother's Apollo lunar lander kits (pre-minifig), and enjoyed the heyday of the early 80's space ship kits.
the lego city line is very enjoyable to me as an adult, and has very few "special" parts.
