For certain authors, the term interactive fiction is no mere pretense.
Emily Short's Galatea is astonishingly beautiful, though a bit difficult to get into if you don't understand the conventions. The important commands are
a topic to ask Galatea about something,
t topic to tell her about something,
g (for again) to repeat the most recent action,
x something to examine something, and
z to pause.
If I were to write interactive fiction, I'd end up with something more like Aisle.
