Here’s Emily Short’s Catalog of Best Interactive Fiction Games, sorted by genre. Great find, not “short” at all.
This (like Edward Picot’s in my previous post) are games in search of a form factor. Playing on PC’s really suck; It would really be nice to be able to play them on portable devices or to have an emulator to make this possible. Update: Apparently Nick Montfort has written up how to run IF on different platforms.
