Galatea

This has to be one of the finest examples of NPC interactivity yet seen in IF. Speaking to an exhibit for 10 or 15 minutes might seem rather strange, but her variety of topics can take you from greek myths to the meaning of life and or death. Recommended for anyone wanting to see developments in IF characterization.

Other games have improved on her initial premise, that being to create the most interactive NPC. Her later works do more interesting things with conversation generally, but don't let this stop you from trying the first real effort to push the boundaries.
