Just found it, here's a few other niche "older" anime:
Real Drive - one of my favorite shows that really shows how far technology could go in the future.
HeatGuy J - another sci-fi futuristic one that premiered on Toonami in 2002; the premise is similar to Blade Runner
Dennou-Coil - this one deals with augmented reality, and it is what I think we're getting closer to the more companies invest in AR. It's also well animated and family friendly.
The Big O - another one that premiered on Toonami 20 or so years ago, I used to make the joke that The Big O was if Batman was an anime with mechs.
Desert Punk - I won't spoil much; post apocalyptic dark comedy.
Aaaaand one of my favorites with one of my favorite anime openings ever:
Kyouran Kazoku Nikki - regular dude gets thrown into a marriage with one of the most powerful beings to exist
See you in a year!
I just want to pilot a Redeemer one. Last. Time.
(because I killed myself with it too)
