I want One Piece to be Zelda style with a big world to explore and dungeons.
I know nothing about this game but my guess is that it's not that kind of game.
It's not Zelda level of course but it's closer than I expected. Exploring is encouraged and the levels are fairly open and dense with content. It's more structured like Monster Hunter with a hub town and open levels outside.
