Zork: The Great Underground Empire is a classic text adventure game. The player begins as an "adventurer" standing near a white house in a nice forest, but soon descends into the Great Underground Empire, where most of the game takes place. The player's quest is to collect the Nineteen Treasures of Zork. 

As was typical for adventure games of its era, Zork does not use graphics. Instead, it communicates with the player via text, and the player interacts with the game by typing commands, such as "examine mailbox" or "take torch". For movement, the player types in geographical directions (such as "north" or "east" - or just "n" and "e"), and can check what items are being carried with the "inventory" command (or just "i"). 

The game was ported over from mainframes in the late 1970s, and is one of the first examples of its genre.


Trivia:

Zork was born on the mainframes of MIT in 1977, and saw its first commercial release on the TRS-80, under the Personal Software (releasers of VisiCalc) label in 1979. The title was a nonsense word used by the creators to label works in progress. Infocom was founded by these creators, Marc Blank, Dave Lebling, Tim Anderson and Bruce Daniels, to create Zork II. 

As part of the release of Zork: Nemesis, Activision released Zork I as freeware on their website. (As of 2001, the links to download the game at activision.com are dead, but the game is available at numerous fan sites.) 

The well-recognized Infocom phrase "Hello, Sailor!" got its start here. Type it in, and you'll get the response "Nothing happens here." Type it in almost any room in any Infocom game, and you'll get the same response. This may be one of the oldest Infocom red herrings around. 

You can find out how many leaves are in the pile of leaves covering the grate in the clearing by typing "count leaves". Strangely enough, it only takes 1 turn to count all the leaves. The actual number of leaves in the pile is 69,105. It's an hex/octal inside joke for programmers. 

There is a location in the game called "Aragain Falls." Spell ARAGAIN backwards, and you'll see something more familiar. 

Typing in "xyzzy" and "plugh" (magic words from an earlier text adventure game), the game comes back with: "A hollow voice says 'Fool.' "

The first commercial release of Zork I (for the TRS-80, distributed by Personal Software) was simply called Zork. The game disk was packaged in a plastic bag with a large manual showing an adventurer outfitted in barbarian guard attacking the troll, with the white house in the background. Such early versions are quite difficult to come by and are highly prized by collectors.
