My mom's friend was an early adopter, mid-90s maybe? I was in 4th grade, and I was obsessed with South Park by proxy (my parents never let me watch it, but since a bunch of other classmates did, I caught on to all the catchphrases and learned how to draw all the characters.) Anyway, I found the South Park website and vaguely remember there being a bunch of mini games in it that I would not stop playing. I basically had to be pried away from the thing.
