The Tutorial List page contains a catalogue of all the known AGI tutorials. A brief decription is included along with links to the original page and a zipped package containing all the files. The cached packaged is available in case the linked site becomes unavailable. If you have trouble accessing a site, try the cached version. While the tutorials have been organised into separate sections, if you're going to create your own game, I suggest at least having a glance at all the available tutorials.
Contents: Game Design | General | Graphics | Sound | Logic | Technical
It's alright knowing how to make a game, but what's the story going to be? How are you going to make some interesting puzzles?
Craft of Adventure, The by Graham Nelson
Published
Graham Nelson wrote the Inform library and compiler to create games that ran under the Infocom z-engine. Basically, it was a complete set of tools to make text adventure games (interactive fiction). Anyway, he also wrote this document that describes the history of the text adventure and the Player's Bill of Rights. This is basically a list of rules that any good adventure game should follow. (eg, you shouldn't have to die to find the answer for a puzzle)

Multiple Redundant Inventory Items by Andrew Baker
Published
So, anyway, in Voodoo Girl, I decided to give the player the ability to carry around more than one of each particular item. But how to do so?! I wracked my brain, stayed up all night, and sacrificed a chicken to a couple of dark gods I know on a first name basis. Eventually, I just turned on my computer and typed in some code. Hmm, guess I should have tried that first.
