The anime I saw as a child were Pokemon, Yu-Gi-Oh!, a bit of Dragon Ball, DBZ, Sonic X, Mega Man NT Warrior, and maybe an episode or two of Yu Yu Hakusho.
There were others I knew, but wasn't into like Sailor Moon and Cardcaptor Sakura, for obvious reasons. There might be a few I might have left out only because I don't remember the name of them.
Dragon Ball, DBZ, Pokemon, and Yu-Gi-Oh!, I don't have to explain what I liked about it because I'm sure someone already said it. Yu Yu Hakusho was just out of curiosity. Sonic X was because the episodes I started watching were based on Sonic Adventure, which is my favorite Sonic the Hedgehog game, so I lost my mind when I saw it. I wastched Mega Man NT Warrior because I had Mega Man Battle Network 3 White so I though it was cool that it was just like the show... I saw the show first.
I've gone back to YuGiOh and Pokemon and can still somewhat enjoy it. DBZ is hard to go back to so I use Kai as an alternative, replacing the awesome Bruce Faulconer music for the faster paced DBZ experience.
