Galatea

Galatea is an interesting piece of IF.  Rather than going on some dungeon adventure or saving a galaxy, all the player does is engage in a conversation with a sculpture that seems to talk back.  The real trick is knowing what to talk about.  The reader must pick out small details within Galatea's dialogue and learn about what she means.  apparently there are over 72 different endings, which is impressive given that so many branching stories try to keep themselves streamlined in order for the author to keep track of continuity.  I never managed to get to the ending of this.  I guess I'm not much of a social person.
