One Piece Mansion is a quirky real-time strategy and puzzle game for Sony PlayStation 1 that blends elements of management simulation. Released in 2001, the game's genre is a unique mix of strategy and puzzle. Players assume the role of a landlord overseeing an apartment complex, striving to keep tenants happy while thwarting the sabotage efforts of a troublesome rival. The charming 2D graphics and cartoonish aesthetics draw inspiration from the popular manga and anime series One Piece, although the game's content is original and not directly based on the show's plot.
