Akira
Record of Lodoss War (the original one, not Chronicles of the Heroic Knight)
Neon Genesis Evangelion
Visions of Escaflowne
Samurai 7
Vampire Hunter D (the first one)
Ninja Scroll
Appleseed (1988... probably my favorite anime ever)
I'm not really into anime though. It lost a lot of what attracted me to it as a kid when it all became computer generated and traditional cel animation was thrown on the dustbin of history. What I've noticed, is that a lot of the anime now seems like it's made for Western teenagers instead of a domestic Japanese audience. So on the rare occasions that I watch Anime, I gravitate toward stuff from the 80s and early 90s. It had more of a gritty, edgy feel to it without being angsty and that made it more appealing to me as an adult.
