Text adventures provide some of us with our earliest computer game
memories. Click a link below to try out a game right now!
See the Interactive Fiction archive at http://www.ifarchive.org/. These
games are of the "Z-Machine"
specification which are also called Infocom, Inform, and ZCode.
The Zplet Java Zcode interpreter is from http://zplet.sourceforge.net/
Activision's Infocom text adventure collections can be played in this
engine, too, including the very oldest Zork games.
