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.[1] Ports were released for Japanese home computers PC-88, PC-98 and FM-7 in 1985.
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.
The game used the company's existing Hi-Res Adventures engine. Roberta Williams was the designer and writer, and its development took six months and about ten other people—the first example of the modern video game-development model in which programmers, artists, and designers are separate people in a team larger than a few people—worked on the game for a year. Each of the more than 1,300 locations had its own artwork. The company hoped to release Time Zone before Christmas 1981, but did not do so until March 1982.[2] Because of the game's difficulty, Sierra offered a telephone help line that players could call for hints.[3]
BYTE wrote "The Guinness Book of World Records must be getting ready for a computer game category, if Time Zone is any indication of things to come. Without a doubt, it is the longest adventure game to date".[4] The game received a Certificate of Merit in the category of "Best Computer Adventure" at the 4th annual Arkie Awards.[5]: 32
Williams' brother-in-law and fellow employee, John, later said, "It frankly wasn't that good". Time Zone sold poorly; the original retail price of United States dollar $99 (equivalent to $323 in 2024) may make it the most expensive computer game in history after inflation.[2] The game was reissued the year of its release as part of the short-lived SierraVentures line.[6][3]
Edits and submissions to the site (including screenshots, box art, developer information, game summaries, and more) go through a verification process of fact-checking by volunteer "approvers".[2] This lengthy approval process after submission can range from minutes to days or months.[3] The most commonly used sources are the video game's website, packaging, and credit screens. There is a published standard for game information and copy-editing.[4] A ranking system allows users to earn points for contributing accurate information.[5]
Registered users can rate and review games. Users can create private or public "have" and "want" lists, which can generate a list of games available for trade with other registered users. The site contains an integrated forum. Each listed game can have its own sub-forum.

MobyGames was founded on March 1, 1999, by Jim Leonard and Brian Hirt, and joined by David Berk 18 months later, the three of which had been friends since high school.[6][7] Leonard had the idea of sharing information about computer games with a larger audience. The database began with information about games for IBM PC compatibles, relying on the founders' personal collections. Eventually, the site was opened up to allow general users to contribute information.[5] In a 2003 interview, Berk emphasized MobyGames' dedication to taking video games more seriously than broader society and to preserving games for their important cultural influence.[5]
In mid-2010, MobyGames was purchased by GameFly for an undisclosed amount.[8] This was announced to the community post factum , and the site's interface was given an unpopular redesign.[7] A few major contributors left, refusing to do volunteer work for a commercial website.{{Citation needed|date=June 2025} On December 18, 2013, MobyGames was acquired by Jeremiah Freyholtz, owner of Blue Flame Labs (a San Francisco-based game and web development company) and VGBoxArt (a site for fan-made video game box art).[9] Blue Flame Labs reverted MobyGames' interface to its pre-overhaul look and feel,[10] and for the next eight years, the site was run by Freyholtz and Independent Games Festival organizer Simon Carless.[7]
On November 24, 2021, Atari SA announced a potential deal with Blue Flame Labs to purchase MobyGames for $1.5 million.[11] The purchase was completed on 8 March 2022, with Freyholtz remaining as general manager.[12][13][14] Over the next year, the financial boost given by Atari led to a rework of the site being built from scratch with a new backend codebase, as well as updates improving the mobile and desktop user interface.[1] This was accomplished by investing in full-time development of the site instead of its previously part-time development.[15]
In 2024, MobyGames began offering a paid "Pro" membership option for the site to generate additional revenue.[16] Previously, the site had generated income exclusively through banner ads and (from March 2014 onward) a small number of patrons via the Patreon website.[17]
