Words Worth (ワーズ･ワース, Wāzu Wāsu) is a Japanese adult role-playing video game originally released for NEC PC-98 computer systems, and remade for Microsoft Windows.

The English dub is notable for featuring real life porn actresses Jenna Jameson and Nikki Dial.

The gameplay of Words Worth is similar to other fantasy games of the era such as The Elder Scrolls II: Daggerfall but with a tongue and cheek sexual undertone.

The two tribes lived in peace and harmony, their domains separated by the "Words Worth" tablet—a huge monolith slab erected by an almighty creator.

One day, Words Worth was mysteriously destroyed by an unknown entity; its fragments were scattered among the domain of the Tribes of Shadow.

In the first half of the game, Umihara, the main protagonist of The Mystery of Nonomura Hospital, enters the world of Words Worth as summoned by Wortoshika.

The Canada Border Services Agency ruled in 2007 that Words Worth is obscene under subsection 163(8) of the Criminal Code and is prohibited from being brought into the country.
