Zorkis atext adventure gamefirst released in 1977 by developersTim Anderson,Marc Blank,Bruce Daniels,andDave Leblingfor thePDP-10mainframe computer.The original developers and others, as the companyInfocom,expanded and split the game into three titles—ZorkI: The Great Underground Empire,ZorkII: The Wizard of Frobozz,andZorkIII: The Dungeon Master—which were released commercially for a range ofpersonal computersbeginning in 1980. InZork,the player explores the abandoned Great Underground Empire in search of treasure. The player moves between the game's hundreds of locations and interacts with objects by typing commands innatural languagethat the game interprets. The program acts as a narrator, describing the player's location and the results of the player's commands. It has been described as the most famous piece of interactive fiction.

The original game, developed between 1977 and 1979 at theMassachusetts Institute of Technology(MIT), was inspired byColossal Cave Adventure(1976), the first well-known example of interactive fiction and the first well-knownadventure game.The developers wanted to make a similar game that was able to understand more complicated sentences thanAdventure'stwo-word commands. In 1979, they founded Infocom with several other colleagues at the MIT computer center. Blank and Joel Berez created a way to run a smaller portion ofZorkon several brands ofmicrocomputer,letting them commercialize the game as Infocom's first products. The first episode was published byPersonal Softwarein 1980, after which Infocom purchased back the rights and self-published all three episodes beginning in late 1981.

Zorkwas a massive success for Infocom, with sales increasing for years as the market for personal computers expanded. The first episode sold more than 38,000 copies in 1982, and around 150,000 copies in 1984. Collectively, the three episodes sold more than 680,000 copies through 1986, comprising more than one-third of Infocom's sales in this period. Infocom was purchased byActivisionin 1986, leading to newZorkgames beginning in 1987, as well as a series of books. Reviews of the episodes were very positive, with several reviewers callingZorkthe best adventure game to date. Critics regard it asone of the greatest video games.Later historians have noted the game as foundational to the adventure game genre, as well as influencing theMUDandmassively multiplayer online role-playing gamegenres. In 2007,Zorkwas included in thegame canonby theLibrary of Congressas one of the ten most important video games in history.

Gameplay

edit

Zorkis atext-based adventure gamewherein the player explores the ruins of the Great Underground Empire. The player types text commands for theircharacterto traverse locations, solve puzzles, and collect treasure. The game has hundreds of locations, each with a name and description, and the player's commands interact with the objects, obstacles, and creatures within them. Commands can be one or two words (e.g., "get lamp" or "north" ) or more complex phrases (e.g., "put the lamp and sword in the case" ). The command must fit the location's context (e.g., "get lamp" works only if a lamp is present). The program acts as a narrator, describing to the player their location and the results of certain actions. If the game does not understand the player's commands, it asks for the player to retype their actions.[1][2][3]The program's replies are typically in a sarcastic, conversational tone, much as aGame Masterwould use in leading players in atabletop role-playing game.[4]

The original 1977 version of the game was a single release,Zork.When it was converted into a commercial software title, it was divided into three episodes, with new and expanded sections added to the latter two episodes.[1]Much of the game world is composed of puzzles that must eventually be solved, such as a set of buttons on a dam or a maze to be traversed. Some puzzles have more than one solution.[5]For instance, since the "Loud Room" is too overwhelmingly loud for the player to perform actions, the player can either empty the nearby dam to stop the sound of water falling, or shout "echo" in the room to change its acoustics.[3][6]In the first episode, orZorkI,a thief character is wandering the underground as well, taking items that have been left behind or even stealing from the player's possessions.[7]The player can fight or evade the thief, and can recover stolen items from the thief's treasure room.[1][6]Some locations contain antagonists that the player must fight or overcome. Beginning inZorkIIthe player can learn magic spells to use in puzzles and combat.[5]In dark areas, the player must carry a lantern or other light source to avoid being eaten by a monster called a grue.[2][8]There is a limit to how much "inventory" one can carry, determined by the combined weight of objects, rather than the quantity.[1]

A principal goal of each episode is to collect all the treasures, many of which are hidden behind puzzles.[5]As treasures are collected or tasks are accomplished, the player'sscoreincreases, providing a rough measure of how much of the game has been completed. The player may traverse the game world and solve puzzles in almost any order, although some passageways require problem-solving to get through, and some puzzles require the player to possess something gained from solving a different puzzle. InZorkIII,unlike in prior episodes, there is a timed component that directly affects the outcome. An earthquake will occur after about 130 moves, opening one passageway and closing another. In each episode, the treasures are needed to reach the conclusion of the game.[3][9][10]

Plot

edit

Zorkdoes not follow alinear storyline.Most of the setting is established through the game's written descriptions of items and locations, as well as manuals in later game releases. Long before the time the game is set in, the Quendor empire, having conquered everywhere above ground, built a massive cave complex to expand. Two hundred years later, the ruler Lord Dimwit Flathead renamed the empire to the Great Underground Empire and spent his reign building massive, largely pointless projects such as an underground dam and the royal museum. A century later, the empire's overspending caused it to collapse, and all the residents left. The abandoned empire is the setting of the three episodes ofZork.[11]

Zork Ibegins with the unnamed player standing in an open field west of a white house, with a boarded front door; most of the game occurs underground, as do the subsequent episodes. InZorkIIthe player learns of the Flatheads, and meets the Wizard of Frobozz, who was once a respected enchanter but was exiled by Lord Dimwit Flathead when his powers began to fade. The wizard appears randomly throughout the game and casts spells that begin with the letter "F" on the player. These have several effects, such as "Fluoresce", which causes the player to glow, and "Freeze", which keeps the player stuck in place for a few turns. InZorkIIIthe player character gathers the garb of theDungeon Masterto become his successor. Once the player has all the items, they must feed an elderly man, who reveals himself as the Dungeon Master and shows them the doorway leading to the final hallway. After the player solves the final puzzles, the Dungeon Master appears and transforms the player to look like himself, signifying the player's succession to his position.

Development

edit

Inception

edit
Marc Blank in 2018, Bruce Daniels in 2009, and Dave Lebling in 2010

Tim Anderson,Marc Blank,Bruce Daniels,andDave Leblingbegan developingZorkin May 1977. The four were members of the Dynamic Modelling Group, a computer science research division at theMassachusetts Institute of Technology(MIT) Laboratory for Computer Science—Anderson, Blank, and Daniels as students and Lebling as a research staff member.[12]Their work was inspired byColossal Cave Adventure,a text-based game that is the first well-known example of interactive fiction and the first well-knownadventure game.Adventurewas immensely popular among the small population of computer users of the time and a big hit at MIT in early 1977.[13]By the end of May, players had managed to completely solve it.[8]

The four programmers began to design a game that would be a "better" text adventure game, with inputs more complex thanAdventure's two-word commands and puzzles less obtuse.[8]They believed that their division'sMDL programming languagewould be better suited for processing complex text inputs than theFortrancode used inAdventure.[8][14]The group was familiar with creating video games: Blank and Anderson had worked on a multiplayer trivia game calledTrivia(1976), and Lebling was heavily involved withMaze(1973), a multiplayerfirst-person shooterand the first 3D first-person game ever made. Lebling first created anatural language inputsystem, or parser, that could process typed two-word instructions. Anderson and Blank built a small prototype text game to use it.[8][12]Zork'sprototype was built for theDigital Equipment Corporation(DEC)PDP-10mainframe computer,the only system that supported their programming language.[8]

While Lebling took a two-week vacation, Anderson, Blank, and Daniels designed an adventure game concept, which Anderson and Blank then developed as an early version ofZork.This prototype contained simple versions of many concepts seen in the final game, including puzzles and locations. According to Anderson, "it took time for people to learn how to write good problems", and Lebling's first, uncomplex parser was only "almost as smart asAdventure's ". The game was unnamed, but the group had a habit of naming their programs" zork "until they were completed, a term in the MIT community for an in-development program. The group, referring to themselves as the" implementers ", continued working on the game after Lebling returned, adding features and iterating on the parser through June 1977.[8]Grues were added to replace pits that would kill players in the dark; while play-testing, Lebling noticed that his character fell into a pit while in the attic of the house.[12]

Lebling contends thatAdventurewas one ofZork's only influences, as there were few other games to emulate at the time. Although the game's combat is based onDungeons & Dragons,Lebling said the other developers had never played it.[15]He also thought of the parser and associated text responses as taking on the role of the Dungeon Master from aDungeons & Dragonsgame, trying to lead the player through a story solely by describing it; this had also been the idea behind the parser inAdventure.[4][16]

Creation

edit

The developers did not announce their game while it was in development, but a lack of security on the MIT systems meant that anyone who could access the PDP-10 computer over theARPANETcould see what programs were being run. As a result, a small community of people, many of whom had been involved in playing and contributing toTrivia,would "snoop" on the system for new programs. They found the new "Zork" adventure game and spread word of it under that name.[12][17]This community—dozens or possibly hundreds of players, according to Lebling—interacted with the developers as they created the game, playtesting additions and submittingbugreports.[15][17]The implementers added a command transcript feature to keep track of what commands players tried to use unsuccessfully.[15]

By the end of June, the game was approximately half the size of the finalZork,and had a substantial community of players for the time. The group added locations such as a volcano and coal mine, and soon shifted their efforts to improving thegame's engineand adding the ability tosave the player's progressin the game. Following user requests, they also added the ability for the game to run on PDP-10 computers running different operating systems—TENEXandTOPS-20—which were much more popular than theIncompatible Timesharing Systemoperating system the MIT computer used. These users then set up a mailing list to distribute updates to the game. The developers returned to creating new content in the fall of 1977, adding the "Alice in Wonderland" section and a system for fighting enemies.[17]

Around this time, community member Ted Hess at DEC decoded theprotectionsthe group had made for thesource code,and another DEC employee, Bob Supnik, created aportof the game to Fortran. This port, released in March 1978, opened the game to a wider set of players without access to a PDP-10 mainframe.[17][18]At the time, the team had decided to give the game an actual name besides "zork", and choseDungeon.This name was used for the Fortran version, which was spread throughthe DEC users groupas one of its most popular pieces of software.TSR Hobbiesclaimed the title violated their trademark forDungeons & Dragons,and the developers reverted to their original title.[17]

Over the course of 1978, the team added the bank and Royal Zork Puzzle Museum sections, along with some puzzles and ideas suggested by players. The last puzzle was added in February 1979, though the team continued to release bug fix updates until the final update in January 1981. Anderson attributes this to the team running out of ideas and time, and having run out of space in the onemegabyteofmemoryallocated for the game.[17]

Very little of the game was planned ahead of time, nor were aspects of the game specific to one developer; instead, whenever one of the developers had an idea they liked, that developer would add it to the game, developing the concept and writing the text to go with it. According to Lebling, Blank ended up focusing mostly on the parser, Anderson on the game code, Blank and Daniels on new puzzles, and Lebling on descriptions of locations.[15]Anderson says that Blank wrote "40 or 50" iterations of the parser, and describes Daniels as designing puzzles that were then largely implemented by the others. He credits Blank with vehicles and saving, and Lebling with the robot, grues, and the fighting system.[17]To immerse the player in the game, the developers decided not to describe the player character, removing any accidental descriptions orgendered pronouns.[15]The text responses to the player's commands were frequently opinionated and sarcastic, a design choice that mirrored the group's speaking patterns. The team felt it would both make the system feel less like a computer and also train the player to write commands in a way that the parser could understand rather than ways it would misinterpret.[4]

Infocom

edit

In 1979, Anderson, Blank, Lebling, and five other members of the Dynamic Modelling GroupincorporatedInfocom as asoftware companyfor members to join after leaving MIT.[19]No specific projects were initially agreed upon and Infocom had no paid employees, but discussions were focused on developing software forsmaller mainframe computers.[19][20]Blank and Joel Berez came up with a plan to makeZorkwork on personalmicrocomputers,which were then beginning to become popular and which would greatly expand the audience for the game. Although microcomputers had very limited memory space compared to mainframe computers, they felt the project might be viable usingfloppy disksand a custom programming language if the game was cut into two pieces.[20]

The pair worked on the project through the summer and fall of 1979 without pay, as the new company had the funds for only the computers. They ported the game to a new Zork Implementation Language (ZIL), which would then be run on a standardized "Z-machine"software-based computer. For each type of microcomputer they wanted to releaseZorkor other ZIL-based games on, they could write an interpreter program that could run the Z-Machine instead of rewriting each game. Lebling dividedZorkin half to create standalone episodes, modifying the game's layout to improve its flow and disconnecting locations now in separate episodes.[20]

By the end of 1979 Berez had been elected the company's president. The core game was complete, but it had been run only onDECSYSTEM-20andPDP-11mainframe computers. Infocom purchased aTRS-80personal computer early in 1980, which could run the game after Blank and Scott Cutler created an interpreter program. Infocom began preparing to release the first section under the titleZork: The Great Underground Empire – PartI.Mike Dornbrook, who had never played the game, tested it as an audience surrogate. He felt that the game would be wildly successful and develop a cult following, and urged Infocom to produce tie-in products like maps, hints, and shirts. The rest of the company was not convinced enough to start producing any such add-ons, but they did add an object in the game that gave an address for players to mail in for maps and hints in case it proved popular.[20]

The game now complete, the company began looking for a professional publisher with store and distributor connections. They felt this was preferable toself-publishing.Berez approachedMicrosoft,who declined based on the game competing withMicrosoft Adventure(1979), their version ofAdventure.Microsoft CEOBill Gateswas a fan ofZork,but by the time he heard of the proposal, Infocom was in negotiations with another publisher,Personal Software,one of the first professional software publishing companies. Personal Software agreed to publish the game in June 1980, sending the company anadvance payment.Zork: The Great Underground Empire,also known asZorkIor justZork,was published for the TRS-80 in December 1980. Since Personal Software declined to publish the 1979 PDP-11 version of the game, Infocom sold some copies earlier in the year after announcing it to PDP-11 user groups. Lebling later recalled that about twenty floppy disk copies were sold directly with Anderson's typewritten manual.[4][20]

By the end of 1980, anApple IIversion ofZorkIwas completed and sold through Personal Software. Infocom began receiving requests for hints and maps as predicted, and Berez began handling map and poster orders while Dornbrook wrote customized hints for players; in September 1981 he founded the Zork Users Group as a separate company to handle allmail ordersales and hint requests.[20][21]Infocom eventually produced hint booklets with progressive answers to questions written ininvisible ink,branded asInvisiClues.[20][22]Meanwhile, Lebling worked on converting the second half ofZorkintoZorkII,but in the process thought up several new puzzles for the game.[20]Although as late as December 1980 he toldBytethat it would be a two-part game, it soon became clear that the second half would not fit into the allotted space.[7]As a result, the game was split again intoZorkII: The Wizard of FrobozzandZorkIII: The Dungeon Master.[20]According to Lebling, splitting the game into episodes led to different atmospheres:ZorkIwas focused on exploration andAdventure-style gameplay,IIhad more of a focus on plot and addedmagic spellsto the base game, andIIIwas less straightforward, with time-sensitive aspects.[15]Marc Blank constructedZorkIIIand added gameplay changes such as the modified point system to move the game away from straightforward dungeon exploration.[12]

Zork IIwas offered to Personal Software in April 1981 and the contract was signed in June, but Infocom grew wary of continuing this relationship. The Infocom team felt that Personal Software was not advertisingZorkIvery strongly, and did not seem excited about Infocom's plans forZorkIIIand other planned text adventure games such asDeadlineandStarcross.Personal Software soon stopped publishing entertainment software altogether and rebranded as VisiCorp in 1982 to align with itsVisiCalcspreadsheet software. Rather than find another publisher, Infocom decided to self-publish its games and began renting office space and contracting with production facilities. It bought out Personal Software's stock of AppleIIZorkIcopies and began publishingZorkIandIIdirectly by the end of 1981.ZorkIIIfollowed in the fall of 1982. Infocom developed interpreters for theCommodore 64,Atari 8-bit computers,CP/Msystems, andIBM PC compatibles,and released the episodes ofZorkfor them as well in 1982.[20]

Reception

edit

Sales

edit

Following its 1980 release,ZorkIbecame a bestseller from 1982 through 1985,[23]with 380,000 copies sold by 1986.[24]In its first nine months Personal Software sold 7,500 copies for the TRS-80 and AppleII.[25]Sales ballooned as Infocom began self-publishing the trilogy and the personal computer market expanded.[20][24]ZorkIhad sold 38,000 copies by the end of 1982, nearly 100,000 in 1983, and around 150,000 copies in 1984.[24]Its success outpaced Infocom's later games;Inc.reported in 1983 thatZorkI,only one of Infocom's fifteen released titles, composed twenty percent of their annual sales.[26]ZorkIsales declined beginning in 1985. The second and third parts ofZorkalso sold well, though not as highly as the first: more than 170,000ZorkIIand 130,000ZorkIIIcopies sold by 1986.[24]

Overall sales of the first three episodes reached over 760,000 copies by early 1989.[24]Combined, they sold more than 250,000 copies by 1984,[19]and more than 680,000 copies through 1986, including the 1986Zork Trilogycompilation release. Between 1982 and 1986, theZorktrilogy composed more than one-third of Infocom's two million total game sales.Activisionpurchased Infocom in 1986 and reported that the threeZorkgames and trilogy compilation sold another 80,000 copies by early 1989.[24]

Reviews

edit

The episodes ofZorkwere highly praised in contemporaneous reviews.Byteand80 Micropraised their writing, which theBytereviewer described as "entertaining, eloquent, witty, and precise".[27][28]Reviewers forSoftalkandThe Space Gamerenjoyed how the parser let them input more complex sentences than did earlier games, theSoftalkreview noting that every other game sinceAdventurehad limited the player to two-word phrases, though they also thought players would largely stick with clearer two-word commands.[29][30]80 Microwondered whetherZorkcould ever be completed because of how much the parser let the player do.[28]Byteconcluded that "no single advance in the science ofAdventurehas been as bold and exciting "asZork,a sentiment echoed bySoftalk.[27][29]

In the years after its release,ZorkIreceived more reviews praising the game in relation toAdventureand the genre.Jerry Pournellerecommended the game in his long-runningBytecolumn, stating in 1983 that "if you likedAdventureand wanted more... I guarantee you'll loveZork".[31]Computer Gaming Worldin 1982,PC Magazinein 1982, andSoftSidein 1983 all recommended it as a "must-have" for anyone interested in fantasy or adventure games.[32][33][34]Family Computing,in late 1983, proclaimed it a classic of the genre and the game that made the adventure genre more than a novelty.[35]

Reviewers similarly praisedZork'ssecond and third episodes.SoftlinerecommendedZorkIIfor its "well-balanced mix of humor, wit, and wry puns" for both new and experienced players.[36]PC Magazinesaid it would appeal to all players and that the game was challenging, enjoyable, and funny.[37]A reviewer forSoftalksaid it broke away from both the first episode andAdventureto be "fresh and interesting".[38]Some of the puzzles inZorkIIwere later considered "infamously difficult", and in a hint book, Infocom apologized for one puzzle's difficulty and reliance on baseball knowledge.[39][40]Reviews inSoftalkandCreative ComputingnamedZorkIIIas the best in the trilogy.[41][42]PC Worldsaid it was "just as exciting and puzzling asZorkIandII",though its puzzles could be frustrating.[43]K-Powerconcluded thatZorkIIIwas "the most intelligent text game for a microcomputer that we've ever seen".[44]

Commodore Magazine,in June 1983, described the combined trilogy as the most popular adventure game, as well as the best.[45]The Addison-Wesley Book of Atari Software 1984gave all three parts ofZorkan overall A+ rating. It calledZorkI"the definitive adventure game", adding thatZorkII"has the same outstanding command flexibility, wry humor, and word recognition ofZork",and concluded thatZorkIIIwas "perhaps the most entertaining of the three" and "a highwater mark for subtlety and logic".[46]InfoWorld's Essential Guide to Atari Computersrecommended the trilogy as among the best adventure games for the Atari 8-bit computer.[47]

Legacy

edit

Zorkhas been described as "by far the most famous piece of [interactive fiction]" and "the father figure of the genre".[48]Game historian Matt Barton contended that "to say thatZorkis an influential adventure game is like saying theIliadis an influential poem ".[39]Rather than simply influencing games, Barton said it instead showed that the computer could simulate a rich virtual world, and helped lay the foundations of video game concepts around exploring, collecting objects, and overcoming problems.[39][49]Nick Montfort,in his book on interactive fictionTwisty Little Passages: An Approach to Interactive Fiction(2003), suggested thatZork's legacy and influence lay not in its parser or writing, but in the way it modeled the game world as a complex, dynamic space that the player moved through.[1]Janet Murray,inHamlet on the Holodeck(1997), considered this a result of the way the game was programmed compared to other games of the time, with each area, item, and actor modeled as their own object that could act and be acted upon.[50]Historians have argued thatZork,along withColossal Cave Adventure,influenced the creation of theMUDgenre, and through it the more recentmassively multiplayer online role-playing gamegenre.[39][51][52]

The game's natural language parser has been noted as having a strong personality, and it was one of the first games to have one.[4]It has been cited as starting a strong trend in writing for adventure games having "metafictional humor, and tendency towards self-parody".[53]Decades laterZorkis still cited as an inspiration for text interfaces such aschatbots.[54]It has also been used, along with other text adventure games, as a framework for testing natural language processing systems.[55][56][57]

Zorkwas listed on several lists of the best video games more than a decade after release. In 1992Computer Gaming WorldaddedZorkto its Hall of Fame.[58]It was placed on "best games of all time" lists forComputer Gaming WorldandNext Generationin 1996, andNext Generationlisted the entire series as a whole in 1999.[59][60][61]In 2016PC GamerrankedZorkas one of the fifty most important video games ever made for establishing Infocom as a studio and defining an entire generation of adventure games.[62]In 2007Zorkwas listed among the ten "game canon"video games selected for preservation by theLibrary of Congress.[63][64][65]

The grue has been used as a homage to classic, early computer gaming, referenced in games such asNetHack,World of Warcraft,andAlan Wake.[66][67]A reference to grues is also made in title and refrain ofNerdcorerapperMC Frontalot's song "It Is Pitch Dark".[68]Writer Bernard Perron, while discussing horror in video games, stated that being hunted by a grue was a "terrifying situation no player had ever experienced before".[69]IGNregarded the grue as one of the best video game villains, stating that the dialogue "It is pitch black. You are likely to be eaten by a grue" was effective, and how despite some physical characteristics being made clear later, players have their own "utterly personal mental image of what a grue looks like". They noted that while it started as a solution to a game problem, it had evolved to become "one of the chief boogiemen in the early history of video games".[70]

Later games and media

edit

Zorkwas the centerpiece of Infocom's game catalog, and Infocom quickly followed it with several more text adventure games using variants of theZorkcodebase and the Z-machine, each of which sold tens of thousands of copies.[4][24]By 1984, three years after Infocom began self-publishingZork I,Infocom had fifty full-time employees, US$6million in annual sales, and twelve other games released.[19]Infocom internally nicknamed its early games in relation toZork,such as "Zork: the Mystery" (Deadline,1982), "Zorks in Space" (Starcross,1982), andZork IV(Enchanter,1983). By 1986 this had increased to 26 total titles. AlthoughWishbringer: The Magick Stone of Dreams(1985) was ostensibly set in the same world asZork,the company had not made any more officialZorkgames, releasing only aZork Trilogycompilation of all three episodes.[12][20][24]

In 1985 Infocom diversified into professional software by creating arelational databaseproduct calledCornerstone.Poor sales led to financial difficulties and the company was sold to Activision in 1986.[39]Infocom then created two moreZorkgames:Beyond Zork: The Coconut of Quendor(1987), which added a graphical map and more role-playing and combat elements, andZork Zero: The Revenge of Megaboz(1988), a prequel game that added graphical elements and menus as well as graphicalminigames.[71][72]Infocom's tenure under Activision was rocky, and rising costs and falling profits, exacerbated by a lack of new products in 1988, led Activision to close Infocom in 1989.[39][73][74]

Activision returned to the series with severalgraphic adventuregames:Return to Zork(1993),Zork Nemesis: The Forbidden Lands(1996), andZork: Grand Inquisitor(1997).[75][76][77]It also releasedZork: The Undiscovered Underground(1997), a free text adventure game partially written by original Infocom implementers Michael Berlyn and Marc Blank to promoteZork: Grand Inquisitor.[78]In 2009Jolt Online GamingreleasedLegends of Zork,afreemiumbrowser-based online adventure game.[79]

The originalZorkgames have been re-released in several compilations sinceZork Trilogy.They are included inThe Lost Treasures of Infocom(1991),Zork Anthology(1994),Classic Text Adventure Masterpieces of Infocom(1996), andZork Legacy Collection(1996).[80][81][82][83]A graphical port ofZorkIfor thePlayStationandSega Saturnconsoles was produced byShōeishain Japan in 1996, nineteen years after its original release.[84]Unofficial versions ofZorkhave been created for over forty years for a wide range of systems, such as browsers orsmart speakers.[54]

Fourgamebooks,written by Infocom developerSteve Meretzkyand set in theZorkworld, were published in 1983–1984:The Forces of Krill(1983),The Malifestro Quest(1983),The Cavern of Doom(1983), andConquest at Quendor(1984). These books, known collectively as the "Zorkbooks",are presented as interactive fiction in the style of theChoose Your Own Adventureseries, wherein the player makes periodic choices and turns to a page that corresponds to that choice.[85]Two novels were published based on the original game:The Zork ChroniclesbyGeorge Alec Effinger(1990) andThe Lost City of ZorkbyRobin Wayne Bailey(1991).[86][87]In 1996Threshold Entertainmentacquired the rights toZorkand announced plans to create aZorkmovie and live action TV series, though it was never produced.[88][89]
