I really don't know what's considered classic since I missed a lot of anime until more recently. I feel like a lot of the more classic stuff I experienced in manga instead, but I'm not sure.

Growing up, I watched Pokemon, Dragon Ball, Sailor Moon, Card Captors, and whatever else was on the channels I watched cartoons on. I can't remember if I watched these, but I did enjoy the manga for Ranma 1/2 and Ah! My Goddess back then. I had a cousin that was obsessed with anime and manga, and she was the one getting me into stuff like that.

Nowadays I've really enjoyed Trigun, Cowboy Bebop, Akira, all of the Miyazaki movies (I can't remember if Nausicaa is old enough to be classic), Excel Saga and a few others. I just don't know when everything came out so I don't what's classic.
