And what we know, or think we know, about the universe of space and time is changing very quickly.

Probably all the books I've ever written have been efforts to define the boundaries of humanity.

There are interactions with characters within the game which I think are pretty neatly done considering the limitations that you have to work with. I mean, a computer can't really generate a character that talks back and forth with you successfully.

I finally decided one day, reading science fiction magazines of the time, I could do at least as well as some of these people are doing. So I finally made a serious effort.

The Swords were still interesting but by then a cast of characters had started to appear and go on from book to book, and other things about the world began to feel constricting. And there were other things I wanted to do, so I closed the series up and stopped it.
