Hmm. I seem to remember that spinning tops were used competetively way back in the 'olden days', not to be confused with yesteryear. I know it goes much further than this, but "The American Boy's Handy Book" from the turn of the 20th century had plenty of these kinds of good old-fashioned (And reckelssly dangerous) activities for boys to get maimed with. One I actually did was to make a paper kite used to fight another guy. As per the instructions in the book, we tied broken glass onto the string and tails of the kite, trying to cut the other guy's kite free, and thereby win. It's late, and I'm rambling, but maybe there's a collectible game there ;D
