IF Interpreters

Interactive Fiction or text adventures is a fascinating combination of literature and computer
games. Most well known is the Zork-series from Infocom, where you strolled around and
solved problems in "The Great Underground Empire". Infocom and Level 9 made commercial
text adventures in the 1980:s. 
In the past 15 years with better computers, programming languages and internet it has arrived
a great number of games, and most are free to download. Many of those that first got fascinated 
by the original games have moved on and made their own. There is a number of genres and
concepts. The quality varies, however. In almost all games you proceed by finding out the
solutions to trickery problems you encounter.

Here is a presentation of some of the games on this page:

Aisle - A one move and one room game. Easy to play.

Anchorhead - Horrorgame in H.P. Lovecraft's genre. You play the wife of a man that becomes
strange after the move to an anchestry house in the town of Anchorhead. The game is a real adventure
and has an excellent use of time. Something that it is unfortunately quite unique at among IF games.
But, the gore is somewhat exaggerated and I don't like the end. Good for beginners. There is a
walkthrough text available if you get stuck.

Lydia's Heart - Aimed for youngsters, but an excellently written game. Good for beginners.

Desert Heat - This is rather a textbook-adventure than a normal IF game.. You bring the story 
forth by selecting alternatives. Easy to play.

Curses - A big classical puzzle-solving game. Hard.

Divis Mortis
- Very good feeling in this zombie-horror. Focus on survival. I am missing more
moveable zombies.

Fine Tune - 20:s style humor. Sad that the game ends in the middle of the story.

I-0 - A game by Adam Cadre. A girl student get an engine failure in the middle of a desert
on interstate zero.

Leadlight - A 2 word parser game in the style and implementation of the oldest games. 
Funny if you like this type of game.

Party Foul - Escape from a boring party-game.

Savoir-Faire - A proper puzzle-solving game by Emily Short. Unusual kind of magic Hard.
A nobleman returns to his family manor and finds it empty.

Shrapnel - Short game by Adam Cadre where you try to understand what is happening.

Violet - A funny game where you need to write a thousand words task or your
girlfriend will quit.

Varicella - About the intriguer Varicella that needs to get rid of all competitiors and survive
at an italian noble house. An advanced game by Adam Cadre.

Earth and Sky Episode 3 - A superhero-adventure

Blue Lacuna - Discover an island. Might be a good starting-adventure.

Zip-Files with Games and Programs

I have collected some of what I think are the best games in some zip-archives that you can 
download here. First, you must download a zip-archive with the interpreter programs 
needed to play the game files. When you have installed them, it's just to click the game-files. 
In some of the game folders there are additional files like solution-texts and pictures.

How to play

IF is played with text commands. In order for the game to understand it should be simple sentences 
like "unlock door with brass key". As a beginner, you might step through a game with a walkthrough
/solution text to get you started. 

Begin a new game with reading through the texts on the help menu or about. There is usually specific 
information for that game. 

In almost all games you move around by typing the compass directions:
The room description will tell you which exits are available. In some games you can use the 
command "exits".

n, w, e, s, nw, ne, sw, se
up, down
in, out 

l or look
x or examine

t, take or get

Prints the room description again. Sometimes you need to type: "look under table".
A more careful inspection. Usually, you have to use examine all the time on new 
things you discover. Ex: x lamp.
Get something.
Drops something.
There is sometimes a limitation for how much you can carry. You may 
carry more by putting things in for example a rucksack.
Wears something you can wear.
Wait a turn.
Saves a position
Restores a position.

Other common commands are:

put (with in or on)
get off
throw [object] at
say ("word" or "phrase"-must use double quotes)
look (at or in or under)

Conversation with characters you meet:
ask x about y
tell x about y

In other cases the conversation system is usually well described.
talk to x

help     Gives help in most games. 
hint      In some games there is a hint system.

How to create Interactive Fiction

If you would like to create interactive fiction, you'll probably want to look at the two biggest systems: the 
programming languages Inform and TADS. With Inform you create games with file extensions starting 
with z: z5, z8 and zblorb as well as gblorb and .blb. It's the old Infocom system that has been updated. 
The Z-games are opened with Windows Frotz or other Z-interpreter. Gblorb and blb are opened with 
Glulxe and that can be larger games with multimedia like pictures and sounds included. With the TADS 
interpreter you open tads-games with the file extensions .gam and .t3.

Inform is to be recommended to beginners. In the latest version: Inform 7, it uses so-called natural 
english, which means that "The Desert is a room." is a program line. TADS-The Text Adventure
Development System appeals in first place to programmers and especially those competent in C.

Both systems are free to download with extensive documentation. At there are articles 
comparing these two and other systems. 

There is a another system called Adrift where you do not need any programming. You build an 
entire game with an editor. That might be the easiest way to create a text adventure, but it comes
with limitations.

Aaron A Reed has written a book about Inform 7: "Creating Interactive Fiction with Inform 7".
Jim Aikin has written "The Inform 7 Handbook", available as PDF.
