One Piece: Become the Pirate King!

One Piece: Become the Pirate King! is a turn-based strategy game for the handheld WonderSwan console, loosely adapting the events of the East Blue Saga (along with One Piece: The Movie). 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
The game mainly revolves around path-building, with players laying tiles across a grid representing the ocean. Tiles carry three basic path formations - straights, elbows, and crosses - and can be rotated in any direction. Tiles come in two different strengths - light, which can be replaced by another tile, and dark, which stand permanent.

At the start of each turn, the player will be presented with five new tiles, and prompted to add one to their "hand" of tiles.
