Whereas most game developers sold their games mainly in software stores, Infocom also distributed their games via bookstores.

In an attempt to reach out to females, Infocom also produced Plundered Hearts, which required the gamer to take the part of a heroine in a swashbuckling adventure on the high seas, and which required the heroine to use more feminine tactics to win the game, since hacking-and-slashing was not a very ladylike way to behave.

And to compete with the Leisure Suit Larry style games that were also appearing, Infocom also came out with Leather Goddesses of Phobos in 1986, which featured " tame ", " suggestive ", and " lewd " playing modes, and that was notable for including among its " feelies " a " scratch-and-sniff " card with six odors that corresponded to six cues during the game.

Reviewers were also consistently disappointed that Infocom — noted for the natural language syntax of their games — did not include a natural language query ability, which was the most expected feature for this database.

Of six novels published as " Infocom Books " by Avon Books between 1989 – 1991, four were directly based on Zork: The Zork Chronicles by George Alec Effinger ( 1990 ), The Lost City of Zork by Robin W. Bailey ( 1991 ), Wishbringer by Craig Shaw Gardner and Enchanter, also by Bailey.

It was also part of the Infocom Plus range, which required a machine with a minimum of 128K of memory.

It was also the first of the " Interactive Fiction Plus " line, meaning that AMFV had greater memory requirements, unlike earlier Infocom games that used a less advanced version of the company's Z-machine interpreter.

: The large emerald is also one of the Twenty Treasures of Zork from the Infocom text adventure Zork I.

Since all Z-machine games were produced by Infocom, there was also no chance that resources would be shipped in a format which a user's interpreter program could not handle.

This allows authors of modern games to ship one file containing everything needed to play the game, while also allowing the creation of resource files for classic Infocom games without running the risk of copyright infringement by distributing Infocom's Z-machine executable code.

Like most other Infocom games, Zork Zero comes with feelies: a printed calendar titled " The Flathead Calendar 883 " with portraits and biographies of the Twelve Flatheads ( also usable as a 1989 calendar ), folded blueprints with a yellow Post-it note attached, and a scrap of parchment.

Zork Zero was also included in the 1991 collection The Lost Treasures of Infocom, and in the 1996 collection Classic Text Adventure Masterpieces of Infocom, released by Activision under the Infocom brand.

In keeping with another Infocom tradition, these feelies also provided a measure of protection against software piracy.

Besides the high quality of their interactive fiction games, Infocom was also known for feelies: extra items included in each game package related to the story, and sometimes used as copy protection.

Infocom had a reputation for not only creating involving stories, but also for feelies, which were extra items included with each game.

Although this was not the only Infocom game designed in an effort to attract female players ( see also Moonmist ), it is the only game in which the lead character is always female.

It was also the thirty-fifth and last game released by Infocom before parent company Activision closed the Cambridge office, effectively reducing Infocom to a " label " to be applied to later games.

( also known as Leather Goddesses 2 or LGOP2 ) is a graphic adventure game written by Steve Meretzky and published by Activision in 1992 under the Infocom label.

One of the last major text-based games published by a major games company other than Infocom, Amnesia is also the only all-text adventure ever published by EA ( The Hound of Shadow, released by EA in, also was largely text-based but featured static graphical screens in its displays to establish setting and atmosphere ).

Activision finally shut down the Infocom division in 1989, although they released some titles in the 1990s under the Infocom Zork brand.

Personal Software published what would become the first part of the trilogy under the name Zork when it was first released in 1980, but Infocom later handled the distribution of that game and their subsequent games.

* Zork: The Undiscovered Underground ( 1997, written by Michael Berlyn and Marc Blank ( original Infocom implementors ) and released by Activision to promote the release of Zork Grand Inquisitor )

Only two version 1 files are known to have been released by Infocom, and only two of version 2.

The compiler ( called Zilch ) which Infocom used to produce its story files, has never been released, although documentation of the language used ( called ZIL, for Zork Implementation Language ) still exists and an open-source replacement ( called ZILF ) has been written.

DN Games released another version of the game on May 25, 2010 using AGS ( Adventure Game Studio ), having remade the original Infocom game to a point-and-click adventure game.

Bureaucracy is an interactive fiction computer game released by Infocom in 1987, scripted by popular comic science fiction author Douglas Adams.

Like many other Infocom titles, it was released for the IBM PC ( DOS ), Atari 8-bit, Amiga, Apple II, Apple Macintosh, Atari ST and Commodore 64 computers.

Like most Infocom games, thanks to the portable Z-machine, it was released for several platforms simultaneously.

The Lost Treasures of Infocom is a collection of 20 computer games from interactive fiction pioneer Infocom, released in 1991.

It builds upon the Zork and Enchanter series of interactive fiction computer games originally released by Infocom.

Before Infocom released Starcross, it released Zork III, and Deadline before that.

Beyond Zork ( full title: Beyond Zork: The Coconut of Quendor ) is a interactive fiction computer game written by Brian Moriarty and released by Infocom in 1987.

The Lurking Horror is an interactive fiction computer game released by Infocom in 1987.

Despite its relatively high sales figures, Lurking Horror was the only horror game ever released by Infocom.

Typically for an Infocom title, it was released for many popular computer platforms of the time, such as the Macintosh, PC, and the Apple II series.

Although Arthur was one of the last interactive fiction games Infocom released before closing, the packaging still included a modest attempt at the extra objects, or feelies, that had been a long-standing tradition for the company.

Although it is the ninth and last Zork game released by Infocom before the company's closing, Zork Zero takes place before the previous eight games ( Zork I, Zork II, Zork III, Enchanter, Sorcerer, Wishbringer, Spellbreaker and Beyond Zork ).

In a somewhat surprising move given the author's popularity, Adams ' name appears only in small print near the bottom of the box's cover, where a blurb reads " by Douglas Adams and the Staff of Infocom.

The Infocom game, The Hitchhiker's Guide to the Galaxy, was sold with a collection of " props " that included a small bag of " pocket fluff ".

Brainwave Creations was a small game programming company started by Michael Berlyn, formerly of Infocom.

* 69, 105, a number commonly found as an in-joke in many Infocom titles.

* 69105, a number that became somewhat of an in-joke in several Infocom games

The number 69, 105 was used as an in-joke at the United States computer game manufacturer Infocom.

The final paragraph about the Infocom game and the Hitchhiker's script book is omitted, however the phone number for NASA in the included translation of " How to Leave the Planet " has been updated for their new area code.
