I found the interactive fiction information very interesting and wanted to see if there was any game or article that was different to take it even a step further. I found this game called CircumReality
http://www.circumreality.com/index.html
It is a multiplayer interactive fiction game but has a visual screen. The player is still typing in things but they are not searching and exploring the setting, they are searching and exploring the other computer-generated characters. Their whole claim to fame seems to be that they are not “killing” computer-generated characters, but befriending them and exploring their personalities by doing and asking things.
I did not play the game but think that it seems like a very interesting experience. It is in so many words exploring a humans personality as a setting or a landscape and using this to explore the game.
