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.

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

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.

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.

Actually ideas are everywhere. It's the paperwork, that is, sitting down and thinking them into a coherent story, trying to find just the right words, that can and usually does get to be labor.

Mysteries I read for fun, so I will probably never write one, for fear of spoiling the fun.

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.
