In One Piece Mansion, the player acts as mansion manager, striving to make money and build more rooms to make his mansion bigger. In order to achieve this goal, you must keep a crazy assortment of tenants happy by correctly situating them next to each other and keeping them out of trouble.
If a resident gets too stressed, they will leave the mansion, skipping out on rent. If they are happy, occupancy will grow, allowing the player to build a larger mansion. Among the motley crew of tenants are a sumo wrestler, a honeymoon couple, a ninja, and a cat lady. Can they and more live in peace and harmony? Each resident has their own unique personality and personal likes and dislikes.
One Piece Mansion offers players a challenging objective while keeping the mood light-hearted and humorous. As the player places their various tenants, each tenant will react with others around them. This makes for humorous situations and interesting relationships that change each time a new game is started.
Players will need to eject the problem residents while keeping the rest of the complex happy. At any time, a player can decide to move one of their tenants to a different room. The player must be very careful, however, as some tenants simply cannot live next to each other. The challenge of One Piece Mansion is to create a stable, well designed mansion while keeping all residents happy.
