Overview

Infocom games are text adventures where users direct the action by entering short strings of words to give commands when prompted. Generally the program will respond by describing the results of the action, often the contents of a room if the player has moved within the virtual world. The user reads this information, decides what to do, and enters another short series of words. Examples include "go west" or "take flashlight".

Infocom games were written using a roughly LISP

s only once per architecture, rather than once per game. Each game file included a sophisticated parser which allowed the user to type complex instructions to the game. Unlike earlier works of interactive fiction which only understood commands of the form 'verb noun', Infocom's parser could understand a wider variety of sentences. For instance one might "go west", or "go to festeron".

 said of their situation, "It was phenomenal — we had a basement that just printed money."

Reception

Three components proved key to Infocom's success: marketing strategy, rich storytelling and feelies. Whereas most game developers sold their games mainly in software stores, Infocom also distributed their games via bookstores. Since their games were text-based, patrons of bookstores were drawn to the Infocom games as they were already interested in reading. Unlike most computer software, Infocom titles were distributed under a no-returns policy, which allowed them to make money from a single game for a longer period of time.

Next, Infocom titles featured strong storytelling and rich descriptions, eschewing the day's primitive graphic capabilities, allowing users to use their own imaginations for the lavish and exotic locations the games described. Infocom's puzzles were unique in that they were usually tightly integrated into the storyline, and rarely did gamers feel like they were being made to jump through one arbitrary hoop after another, as was the case in many of the competitors' games. The puzzles were logical but also required close attention to the clues and hints given in the story, causing most gamers to keep copious notes as they went along.

Sometimes, though, Infocom threw in puzzles just for the humor of it—if the user never ran into these, they could still finish the game just fine. But discovering these early Easter Eggs was satisfying for some fans of the games. For example, one popular Easter egg was in the Enchanter

game, which involved collecting magic spells to use in accomplishing the quest. One of these was a summoning spell, which the player needed to use to summon certain characters at different parts of the game. At one point the game mentions the "Implementer

 at their computers, surprised at this "bug" in the game and working feverishly to fix it.

Third, the inclusion of "feelies"—imaginative props and extras tied to the game's theme—provided some copy protection against pirating

. Some games were unsolvable without the extra content provided with the boxed game. And because of the cleverness and uniqueness of the feelies, users rarely felt like they were an intrusion or inconvenience, as was the case with most of the other copy-protection schemes of the time.

Although Infocom started out with Zork, and although the Zork world was the centerpiece of their product line throughout the Zork and Enchanter series, the company quickly branched out into a wide variety of story lines: fantasy, science-fiction, mystery, horror, historical adventure, children's stories, and others that defied categories. In an attempt to reach out to females, Infocom also produced Plundered Hearts

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.

Invisiclues

Originally, hints for the game were provided as a "pay-per-hint" service created by Mike Dornbrook called the Zork User's Group (ZUG). Dornbrook also started Infocom's customer newsletter called The New Zork Times to discuss game hints and preview and showcase new products.

The pay-per-hint service eventually led to the development of InvisiClues
InvisiClues
InvisiClues were hint booklets sold by Infocom to help players solve puzzles in their interactive fiction computer games.Before Infocom's games exploded in popularity, players could request hints by mail and receive a type-written sheet in response. When the number of requests proved...

: books with hints, maps, clues and solutions for puzzles in the games. The answers to the puzzles were printed in invisible ink that only became visible with a special marker that was provided with each book. Usually, two or more answers were given for each question that a gamer might have. The first answer would provide a subtle hint, the second a less subtle hint, and so forth until the last one gave an explicit answer. Gamers could thus reveal only the hints that they needed to have to play the game. To prevent the mere questions (printed in normal ink) from giving away too much information about the game, a certain number of misleading fake questions were included in every InvisiClues book. The InvisClues books were regularly ranked in near the top of best seller lists for computer books.

In the Solid Gold line or re-releases InvisiClues were integrated into the game. By typing "HINT" twice the player would open up a screen of possible topics where they could then reveal one hint at a time for each puzzle, just like the books.

Infocom also released a small number of "interactive fiction paperbacks" (gamebooks), which were based on the games and featured the ability to choose a different path through the story. Similar to the Choose Your Own Adventure

series, every couple of pages the book would give the reader the chance to make a choice, such as which direction they wanted to go or how they wanted to respond to another character. The reader would then choose one of the given answers and turn to the appropriate page. These books, however, never did sell particularly well, and quickly disappeared from the bookshelves.

, aimed at capturing the then booming database market for small business. Though this application was hailed upon its release for ease of use, it sold only 10,000 copies; not enough to cover the development expenses.

, so it was not promoted by any of the database consultants that small businesses typically hired to create and maintain their DB applications. 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. And a final disappointment was that Cornerstone was available only for IBM PC

s and not any of the other platforms that Infocom supported for their games; while Cornerstone had been programmed with its own virtual machine for maximum portability, that feature had become essentially irrelevant. Cornerstone used the virtual machine for its processing, resulting in lackluster performance.

Changing marketplace

Whereas Infocom's games had benefited significantly from the portability offered by running on top of a virtual machine, this strategy did not prove to be a significant advantage for Cornerstone; in fact, the virtual machine significantly slowed the database's execution speed. Businesses were moving en masse to the IBM PC platform by that time, so portability was no longer a significant differentiator. Infocom had sunk much of the money from games sales into Cornerstone; this, in addition to a slump in computer game sales, left the company in a very precarious financial position. By the time Infocom removed the copy-protection and reduced the price to less than $100, it was too late, and the market had moved on to other database solutions.

And finally, the game market itself was shifting into graphic games. The 1990s, though, were a turbulent time for graphics development, as the computer industry was collapsing, with long-time computer makers such as Tandy/Radio Shack

 in charge. Davis believed that his company had paid too much for Infocom and initiated a lawsuit against them to recoup some of the cost, along with changing the way Infocom was run. For example:
  • Davis required they use Activision's packaging plant instead of their own in-house one, raising the cost of each package from $0.45 to over $0.90. In addition, the Activision plant made numerous mistakes in packaging where the Infocom one almost never did.
  • Infocom had a successful marketing approach that kept all their games in store inventories for years. Because of this, older titles' sales often kept pace with sales of newer games. For example, because Zork was available for years after its initial release in 1980, it continued to top charts in sales well into the mid-1980s. Activision preferred to market Infocom's games the way they marketed their other titles: replacing older titles with newer ones. While this made sense for the graphically intensive games that made up the rest of Activision's catalog, since Infocom games were text based, it didn't make sense - the newer games didn't have improved text. This marketing approach cut off potential revenue for numerous Infocom titles that had consistently brought in money for several years.
  • Davis required the struggling developer to produce eight titles a year. Infocom had traditionally produced about four games per year with more staff than they had post-merger.
  • Davis pushed Infocom to release more graphical games, but the one they did release, Fooblitzky

    , bombed. This was, in part, due to Infocom's long-standing rule of maximum portability; a game that could display graphics on a number of different systems couldn't take advantage of the strengths of any of them.
  • The cost of acquisition was amortized by deducting it from Infocom's operating revenue during the next several years.

Closure and afterward

Rising costs and falling profits, exacerbated by the lack of new products in 1988 and technical issues with its MS-DOS products, caused Activision finally to pull the plug on Infocom in 1989.
