The Berserkers have been with me for about forty years, and we're not done yet.

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.

There's a big overlap with the people you meet at the fantasy and science fiction cons.

If people ask me for the ingredients of success, I say one is talent, two is stubbornness or determination, and third is sheer luck. You have to have two out of the three. Any two will probably do.

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

I don't know why a computer game can't be an art form just as a puppet show or an opera is. I'm still interested in computer games as something I would like to work on someday.

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.

I am generally way out of touch with trends, except now and then I am surprised to find myself leading one, like sympathetic vampires.

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.

Only towards the end of this process are any of the chapters in fully readable condition, a state of affairs that used to alarm my wife. But Joan's got used to it.

I doubt I'll ever do another book collaboration; I've been spoiled. Roger and I both happened to move to New Mexico at about the same time, when we each had a family of young kids to raise. Socializing seemed to lead naturally to working together.

I suspect that writer's block afflicts mainly people who have some stable and ample source of income outside of writing. So far it hasn't been a problem.

My gut feeling is that paper and ink are going to be with us for a long time yet, and in substantial quantities, though certainly books are now going to be available in other forms.

The advice would be the same for any kind of fiction. Keep writing, and keep sending things out, not to friends and relatives, but to people who have the power to buy. A lot of additional, useful tips could be added, but this is fundamental.

I wrote speculative fiction because I loved to read it, and thought I could do better than some of the people who were getting published.

I guess if one set of my books was selling like Stephen King's, and the other wasn't selling at all, editors would want me to do the ones that sold like Stephen King's. But they seem to be willing to let me pick what I want to do next.

I had immediate success in the sense that I sold something right off the bat. I thought it was going to be a piece of cake and it really wasn't. I have drawers full of - or I did have - drawers full of rejection slips.

The comments I most appreciate come from ordinary readers who've happened on one of my books at some time of stress in their lives, and who actually credit the book with helping them through a bad time. It's happened a few times in forty years.
