Morrow and Halliday decided to start their own videogame company, Gregarious Games, which initially operated out of Morrow’s basement. Halliday programmed new versions of Anorak’s Quest for the Atari 800XL, Apple II, and Commodore 64 computers, and Morrow began placing ads for the game in the back of several computer magazines. Within six months, Anorak’s Quest became a national bestseller.
