In 1937, Leiber and his college friend [[Harry Otto Fischer]] created a complex [[Wargaming|wargame]] set within the world of Nehwon, which Fischer had helped to create.  Later, they created a simplified board game entitled simply ''[[Lankhmar (board game)|Lankhmar]]'' which was released by [[TSR, Inc.|TSR]] in 1976.  This is a rare case of a game [[adaptation]] written by the creators of the stories that the game is based on.

Nehwon, and some of its more interesting inhabitants, are described in the early ''[[Dungeons & Dragons]]'' supplement ''[[Deities and Demigods]]'', and the stories themselves were a significant influence on the role-playing game.

In 1986, Fafhrd and the Gray Mouser were featured in a 1-on-1 Adventure Gamebook set, ''Dragonsword of Lankhmar''. One player controlled Fafhrd and the Gray Mouser, who were trying to find a magical sword beneath an altar (just which one, they were not sure) in Lankhmar. The other player controlled assassins from the local thieves' guild, who were trying to kill the famous rogues for operating in the city without permission from the guild.
