When I was a kid I played with Lego. Every free moment was spent with Lego. My parents were continually warned by their friends and even our family doctor that I shouldn't spend so much time playing with Lego. It was 'addictive' and the time I spent playing with Lego was time I wasn't concentrating on homework, throwing ball, and other important things a child should be doing. The point is, every generation tends to have a play devil, the thing that will lead to the destruction of our society and hamper our children's long term success.
