This is probably somewhat outside the scope of IF/text adventure, but I have just begun reading the interactive science fiction novel Portal by Rob Swigart and Activision (1986). I’m not that far into it yet, but what I have read is really intriguing.
You have to piece together the story by reading chunks from different databases, some of which are DNAcode-protected. As I said, just getting started, but very interesting.
Just thought I’d put this on here, in case anyone is interested or has any experience with this novel/game to share.
