I was a ACM National lecturer and gave a formal version of my Computer Faire talk, EPIC COMPUTER GAMES, written with Lee Hoevel. The talk (and article) described a visit-travel-explore-discover game played in a virtual space. It suggested that the user interface could be natural language, which could be done using an Eliza-like system. Computers then were mostly textual so instead of shooting with laser guns disputes were to be resolved by solving problems or completing riddles.
