Do you miss those old text adventures? You can play many of them online at WildBill’s Infocom Text Adventure Collection. Wildbill found a Java-based game interpreter and made the games available. Due to limitations of Java, you can’t save your game, but they are still fun to play.
In his collection, you’ll find Zork 1, 2, and 3, Hitchhiker’s Guide To The Galaxy, Bureaucracy, and Leather Goddesses of Phobos.
The collection can be found at
There are a few other links, including one for the Interactive Fiction Archive. Believe it or not, people are still cranking out games in this format and there are a number of gems in the archive.
