Galatea is set in an artificial intelligence exhibit. Galatea, a stone woman brought to life, has mistakenly (or purposefully) been placed here.
You are a journalist, interviewing her to determine how good her "artificial intelligence" is. The answers can lead to anger, romance, supernatural effects, and a host of other possibilities.
It is a fun game to play through a few times. The conversation system is just asking her about more and more things, but the variety is endless.
This game was groundbreaking when it was first released, although later innovations have improved on it (such as the major NPC in Blue Lacuna). This game remains an enjoyable classic, because it isn't just technically impressive, it's enjoyable.
