Born in the 90s, my favourite era is the 80s-early 2000s era anime as a lot of the studios put in a lot more effort at least from my opinion lol.
I do like some modern era, ones that stand out are still Gundam(big gundam fan), AOT, Jojo Bizarre Adventure, One punch man S1, Castlevania and Baki.
Just to name a few from 80,90s and early 2000s:
- Gundam (Original to 00)
- Macross (Original, Plus, Zero and Frontier)
-Guyver The Bio booster armor
-Dragonball and Z
- Saint Seiya will be on my list once after I finish watching it
- Tenchi Muyo
- Neon Genesis Evangelion
I should really compile a anime list of OVAs, series and movies i've watched on my anime list but never got round to doing it.
Given that list, it sounds like you like Sci-Fi (yeah, DBZ is SciFi, lol)
Steins;Gate might be up your alley (from 2011), its arguably a new-style anime but kind of feels retro in its own way. Maybe Time of Eve (2008), but there's almost no action in that one... and instead leans dramatic sci-fi.
Its hard for me to think of a recent hard or soft Sci-Fi anime that I liked, unfortunately. It seems like that was a 90s thing, and kinda died out by the late 00s. Steins;Gate is the newest thing I can think of...
EDIT: Okay, Dragonball Super is different, but it continues the story of DBZ. The arc around episode ~50 or so was incredibly good (Future Trunks comes back!!! ).
With Saint Seiya, I'm thinking you might like "Super-Macho Tall Tales". (I mean, there's that one dude in Saint Seiya literally trained by choking bears in a forest... amirite?). Golden Kamuey reminds me of Saint Seiya in that regards: tall tales and urban legends with regards to survival, soldiers, and the like.
Golden Kamuy does this "meme face" thing that's popular today, but I don't really like that (seems to be the influence of Jojo...). But aside from the meme-faces, the story is largely about early 1900s urban legends and tall tales. Secret maps leading to gold: Ainu sayings ("if you crawl into a cave with a bear in it, it will think of you as kin and won't attack"), cooking in the woods, etc. etc. Its pretty ridiculous at face value, but so was Saint Seiya. So maybe that's something recent you can check out.
Also the meme-face thing... so you're aware that it will happen a lot in this show.
But it really does feel like a proper wilderness / survival show most of the time.
