Time Zone allows players to travel through time and across the globe solving puzzles while meeting famous historical figures such as Benjamin Franklin, Cleopatra, and Julius Caesar. The game has static pictures and a text parser that understands two-word commands.

Time Zone is a multi-disk graphical adventure game written and directed by Roberta Williams for the Apple II. Developed in 1981 and released in 1982 by On-Line Systems (later Sierra Entertainment), the game was shipped with six double-sided floppy disks and contained 1,500 areas (screens) to explore along with 39 scenarios to solve. Produced at a time when most games rarely took up more than one side of a floppy, Time Zone is one of the first games of this magnitude released for home computer systems. Ports were released for Japanese home computers PC-88, PC-98 and FM-7 in 1985.
