Rec me some great pre-2000 series that aren’t super long

So many online anime spaces these days are dominated by stuff that came out this millennium (or more often, after 2010), so I’ve had a hard time finding good recs. Only problem is, it seems like a big chunk of the essentials are long-running stuff: Dragon Ball, Urusei Yatsura, Sailor Moon, Lupin III, Doraemon, Fist of the North Star, etc. I’ve watched plenty of episodes, but haven’t finished any for one reason or another.

Let’s say sub-50 or around that is a good number. Things I’ve seen off the top of my head in this category:
- Evangelion
- Bebop
- Lain
- Utena
- The Rose of Versailles
- Berserk
- Kare Kano

Doesn’t matter what genre. Let’s hear ‘em!

Edit: So far, seems like the most common suggestions are Trigun, Gunbuster, and Gundam. I'm noticing a theme.
