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.

Research is of considerable importance in certain fields, such as science and history.

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.

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 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.

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.

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.
