It was at Lucasfilm that he met Chip Morningstar, who was beginning design on the Habitat project, a groundbreaking graphical multiplayer adventure game.

When the project received funding, Morningstar hired Farmer for the team, along with others such as Aric Wilmunder, Janet Hunter, Noah Falstein and Ron Gilbert.
