Somebody implemented an interactive fiction adventure on a Jabber server. add soul_tracker.jabber.org to your contact list and send something to that account.

PiFi is a Zcode interpreter written in Python. Great for playing your favorite Infocom games.

The text adventure version of the movie The Dark Crystal is now playable online.

A framework written in python for writing a MUD or interactivefiction. Can run as a console app or with a simple GUI that uses tkInter. Even has a webapp. Has a re-implementation of LPC-MUD's soul.c parser. Seems to be very complete insofar as IF is concerned, maybe the soul module will give me some hints for writing a parser.

A system for writing interactive fiction that models the discourse and dialogue as well as the world in such a way that it can drift slowly over time (i.e., as players interact with it). Allows for different narrative systems (flashbacks, intercutting, out of order). Requires some knowledge of narrative theory, IF, and python to really use. Useful to people researching computational intelligence and development systems. Seems like it's for use on top of other text-based systems instead of implementing a full one.

Jason Scott of textfiles.com is at it again - this time he's making a documentary about interactive fiction - text-based adventures, in other words, like Zork.
