Lego was a huge one for me -- I loved having a giant tupperware box of random pieces and no instructions. Another big one, but one that I don't see often, is Capsela (http://www.wikiwand.com/en/Capsela http://www.wikiwand.com/en/Capsela). I loved the fact that it actually moved and did stuff and could roll or float. Nowadays, if I were a kid, I'd probably play with one of the programmable Lego sets until it broke or broke something else!
