And the plastic used in those early dice included in some of the older D&D editions was SO poor. I still have a d12 and d20 from a set I bought in 1977, and they are both worn to nearly perfect spheres - they wobble around forever before they finally settle on a number.
Then I discovered that I could use my "Teachers Choice" money to buy a Pound o' Dice bag, which was cool (I've even given some of those away to students who liked the pretty colors) and other unusual looking dice. (I do teach probability, so it was connected to the curriculum. And I can take them home over the summer ....)
Too bad I can't get my kids into this stuff. It's computer games for them and that's it.
