One Piece: Become the Pirate King!

One Piece: Become the Pirate King! is a turn-based strategy game for the handheld WonderSwan console. Designed by Soft Machine and published by Bandai, it was released on July 19, 2000 - the first official video game under the One Piece license.

Following the game's release, five more One Piece games would be produced for WonderSwan consoles, though Become the Pirate King! remains the only one compatible with the original monochromatic system.

Gameplay
It's a strategy RPG game revolving around pipes and playing cards. Your task is to construct a path across the water logged area to the enemy's base using pipes. Along the way, you may encounter surprise enemy attacks and these are also dealt with in a battle of pipes but on a much smaller scale.

The graphics they use is similar to the manga illustrations to make the most of the black and white display.
