I hate these lists. They always put some extremely boring toy on there. This one had Viewmaster (I HATED those things) and Rubik's Cube. I grew up in the 80's and I think every time I saw a Rubik's Cube, I picked it up for a few minutes then went on to something better. Another lists I saw had Slinky (great I guess if you were in the 50's with nothing better) and Hula Hoop. Hula Hoop is only interesting when you become a teenager and see attractive girls using them. :lol
I think out of every toy I had growing up including, Star Wars, Transformers, He-Man, GI Joe, etc., out of all of those I played with my LEGO toys more than anything. So I'd put LEGO at the top. GI Joe would probably be second and Star Wars third (which is ironic now...).
