Wow. I honestly don't even remember. I came across my first one back in 1998, possibly 1997, but there was a few that I read at the time. They include:
Ian Kim's Genesis
Clay's Aphasia
a bunch of round robin comics at a comic artist community; my favorite one was called Mystic Child, I... THINK? The only title from that collection I remember clearly is Point Blank Assassin, which I didn't actually follow, ironically.
I know there were more, but I can't remember!
So I'm the only one so far who started in the 20th century? XD
