ranma 1/2
rurouni kenshin

favorite old anime
 

I like sailor moon, Cyborg 009 and Hi5. others may not like the concept but i find it entertaining.

Ronin Warriors

If these examples are old, then so am I. Very very old.

How about some Kimagure Orange Road, or Touch, or Rose of Versailles, or Ace wo Nerae?

Interesting how people posting here think that an anime from roughly 10 years ago is old? Heh you dont get that with books...
And are we restricted to anime series? I'm really surprised no-ones mentioned either Akira or Ghost in the Shell (the original movie). Or Guyver, though I never did like all that violence. Anyway here goes:
Evangelion
Nadesico
Gundam (pick one. Any one)
Cardcaptor Sakura (yes, I liked it. So sue me)
DBZ


Oh, and Digimon.

What? I'm a big kid with a cold and heratless...heart....*goes back to just reading this place again*

Rurouni Kenshin and Slayers are probably the oldest anime series in which I still frequently watch and love even though 12 years isn't very long they still rank in as the oldest.

I'd have to say Gundam Wing and Rurouni Kenshin those were the 2 first anime's that I ever watched ^^

Um. Yu Yu Hakusho, Cowboy Bebop and Dragon Ball. ^.^ OH! And Sailor Moon. XD

Not totally sure what qualifies as "old," but:

Cowboy Bebop
Trigun
Weib Kreuz (Knight Hunters)
Lost Universe (it's a riot)
Berserk (the ending literally rips your heart out and feeds it to you -- but, hey, I liked the show)

h2
touch tv
maison ikkoku
space adventure cobra
city hunter
kimagure orange road
samurai pizza cats (lmao it was the 1st anime i ever watched)
