Habitat
Social Software, back in 1986, had not yet the name recognition it has now. I remmeber an article in Compute! magazine about Habitat, a sort of Metaverse (actually Stephenson mentions Habitat as a predecessor of his Metaverse) or proto-MMORPG.
Habitat presents its users with a real-time animated view into an online simulated world in which users can communicate, play games, go on adventures, fall in love, get married, get divorced, start businesses, found religions, wage wars, protest against them, and experiment with self-government.
And Morningstar went to explain the lessons deried from their experience, among those: "Detailed central planning is impossible; don't even try."
It still applies.
