Many shonen manga lose there sense of adventure over the course of the series and focus on power levels, but one piece seemed to keep true to the adventure narrative despite what some people say.
>Dragon ball
No more exploring new lands, everyone is now married with children. w
>Jojo
After part 2 it just didn't feel like much of an adventure, 3 and 5 , 6 was enemy of the week
whilst 4 was mostly around moria,
>Yugioh
We didn't seem many new games after a certain point, it was cool seeing current trends and various forms of games in Kazuki Takahashi style
>Naruto
Aside from anime only filler and novels, it became focused on fights, and hardly any ventures to new lands . Honestly I would have liked to see more about the underworld and seedy dealings
>Gash Bell
It was always about the mamono battles, but after faudo, there was no sense of exploration anymore. Well it was near the end anyway
One piece on the other hand
>explore strange new lands on the regular
>Meet natives that can fend for themselves and aren't helpless
Samurai, Minks, Many of the colleseum figherers,t etc.
>powercreep
Unlinke many of the others we see high level dudes early on in the story, and our protagonists aren't potrayed to be the strongest dudes about.
i.e. Mihawk, Dragon in Lougetown, Dorry and Broggy with the elbaf spear.
>Long overarching side stories with build up
Poneglyphs, ancient kingdom shit, vegapunk stuff, military retaliation, etc.
I am not sure, the others just seemed to focus on the battle at hand and nothing else .
