I was working on implementing a minimap in my game engine today, and got to thinking. What was the first game that implemented a minimap?
The earliest that I can remember, as far as a minimap as we understand it in strategy or simulation games, would probably be Civilization, but I'm sure that there is something that predates that. I want to think that I remember that one of the Zork games had a basic automapping feature, but that's not quite the same.
Google is being surprisingly unhelpful on the subject...
