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

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 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 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.

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.
