1 Clannad
2 AOT
3 Full metal alchemist
4 Jjba
5 Steins gate
honestly they are all on the 1st spot, but if i had to really rate at gunpoint this would be my tierlist
edit: fuck i forgot about vinland saga, oh well
Bofuri doesn’t just focus on world building, unique scenario and floor monsters, but the server events and PVP explore characters and guild too. Anime isn’t rushed like solo levelling with constant story progress, but u get to enjoy the immersion, kind of like HxH Greed Island arc. Log Horizon is a close 2nd on the fantasy/isekai/game genre.
That's why it goes under bias top 5. There's really not much good Video Game Isekai other than Log Horizon/Overlord/The King's Avatar/SLF. Can't put SLF yet cause it barely scratches the surface.
For fantasy I do rate Made In Abyss better overall as a show (that's why it goes under non bias top 5), but the 3 by 3 anime its more reflective of your personality. Niche anime don't usually make "general top 5" lists for a reason. Detective Conan is my personal top 1 cause I've seen over 1000+ episodes.
I never watched that much anime, but when i was younger i really liked those:
Samurai X
Slam Dunk
Dragon Ball (+ the Z saga)
Saint Seiya
Captain Tsubasa
All can be over analyzed, but those had me hooked up really waiting for new episodes.
I tried to watch some "newer" series but didn't hook that much: Yowamushi Pedal (since i like bikes for years) and Blue Lock, meh maybe i'm too old.
