Back in 1980, how would
you have advertised a game that deals with monsters, treasures and
dark caves? Well, probably you would have aimed it at the computer
nerds, who were about the entire populace that played games about
monsters, treasures and dark caves.
And that is just what
Personal Software, Inc., at that time publishers of Infocom, did
with Zork (from Byte Magazine, December 1980).
No trace yet of the later
sophistication that Infocom sold the games with in bookstores.
