This site tries to list all adventure games (interactive fiction) produced over the years. When I say "adventure", I mean text adventures and their graphical decendants, but I don't include RPGs. For a more detailed description of what's included here and not, see the FAQ.
This search engine is not yet very smart, so please treat it kindly. ;-) If you feed it more than one word, it will look for them in that order. Case is not important, but punctuation is. Actually, you can feed it a regular expression and if it's legal in Perl, it will work (if you didn't understand the last sentence, it doesn't matter).
Before I end, I just want to mention The Interactive Fiction Archive. For those of you who don't already know, this is an archive for anonymous ftp that is a goldmine for anyone interested in interactive fiction. It contains loads of playable games, a lot of articles and information about interactive fiction and quite a few different systems for creating your own games. It is now maintained by David Kinder and Stephen Granade who are doing a great job.
Thanks to Maike Liedtke for the Adventureland logo.
Adventureland was created by Hans Persson and is now maintained by Stefan Meier.
