There's actually some difficulty to be had, too, even if it's just dodging out of giant attacks or protecting allies from getting mauled across the map. There's a hefty amount of content in One Piece 3, including a giant story mode and a Dream Log, which has players moving on a 3D map linking islands together to unlock characters. (If you've watched One Piece to around episode 500, you'll understand.) Though, only time will tell. Many consider this to be the definitive One Piece experience and argue that the upcoming Pirate Warriors 4 isn't doing enough to include the pre-timeskip arc. Not only can you get it for around $10 to $15 (keep an eye out if you're on Switch), but it's the only game on this list where you can be a giant Minotaur with a snot bubble hanging from its nose.
One Piece: Pirate Warriors 3 is a joy to play.
