As my journey into weebdom continues (maybe I could do a Youtube miniseries on that) I have another recommendation request. I remember someone once telling me that I would like My Hero Academia since I am a fan of old school super-hero comics and I've heard My Hero Academia be described as a love letter to comic books. I plan on getting that omnibus soon but I would also like to know what are some good Sci-Fi/Fantasy anime or mangas? Probably the very first anime I ever saw was Robotech because my older brother was really into it when I was a kid. I read his Robotech book over and over. As for fantasy, I guess Howl's Moving Castle would count? I actually learned recently that was based on a manga so I want to check that out.
So is there any good sci-fi anime/manga y'all could recommend?
It really depends on your taste at the time as there is SO many to choose from that it's more finding your niche than anything else.
Like do you want sci fi but with a lot deeper characters and story, Steins Gate, Gundam 00, 86, Psycho-pass (1st season) comes to mind.
Something light hearted? Trapped in a dating Sim is technically sci fi (though as the MC says himself, it's like they took everything and threw it at the wall in this world)
Or something unique, Meglobox has the art style of the 90s but a killer soundtrack and great story.
As Gemmauger recommended, I'd use lists like that to do a search on what you want to see, I have only kept on board to most of the current releases thanks to a few YouTubers that check the new releases.
All those sound like they are worth checking out.
