After 10+ years of watching anime, I have realized that I no longer enjoy it. No new good anime are released, so it's time to drop it and never come back. I particularly like the anime that are mentally engaging or have some philosophical takes (esp. the ones that reference other works).
Here are my favorites
TOP 7 - nothing compares to them so easy to choose,
1. Texhnolyze
2. Legend of the Galactic Heroes
3. Ergo Proxy
4. Psycho Pass season 1
5. Monster
6. Akagi
7. Ghost in the Shell
The rest, in no particular order:
One Outs
Zetsuen no Tempest
Xam'd: Lost Memories
Book of Bantorra
Shinsekai Yori
Fullmetal Alchemist (2003)
Lain
Suisei No Gargantia
Haruhi Suzumiya
Ping Pong the Animation
Spice and Wolf
Kaiba
Paranoia Agent
Kara no Kyoukai
