When I was a kid we played with marbles, that's the only thing we did during recess for some time. Then came the POGs, or as we called them (for some reason) "caps". MY favorite ones were the Mortal Kombat. There was also a time period when the boys collected football- and hockeycards while the girls kept to bookmarks. I'm not sure if you call it bookmarks in the US or whatever English-speaking country you're from, but this is what I mean:
Big ones, especially the Angels, were worth a lot.
Then I spent the remaining years of my childhood, before being hit hard my puberty and the horrible teenage years, playing Super Nintendo and watching Disney movies.
