Love it but I was always a HUGE fan of Lego
I had one of these back in the 70's and loved it http://www.brickset.com/detail/?Set=264-1
The smooth tiles were so much fun for other projects such as building a small house with lots of details (my windows had shutters) and using a smooth tiles to 'make' a bed?
Perhaps that's why I lost interest in this room set too soon. I always liked to look through the small houses windows and imagine living there.
