Series Books vs Stand Alone

At one of my author's meetings, I was asked why I don't write series books using the same character(s). Group consensus was that series books are the way to make money - by keeping your readers coming back. And, that book publishers are more likely to look at series writers because it affords them a greater opportunity for a return on their investment.

I'm not opposed to series writing, and have the potential to develop a series using one of the characters I've used in two books, but I'm not ready for that at this point in my career.

One pet peeve I have with some of those that do write series, is that often there is no ending to the story and I must get the next book to see where the story goes. For that reason, I usually avoid reading authors that use Book One in the title. I don't remember a book one with Treasure Island or the other classics. But then again, the writing world has changed with the advent of electronics and reader's tastes.

One series writer I do enjoy reading is Janet Evanovich. Now she writes a beginning, middle, and end.

For the time being, I am happy writing independent stories and characters. My hope, as many other authors have said, is to entertain the reader sufficiently to instill a desire for them to try more than one of my books.

I'd like to know your thoughts about series versus stand-alone writing.
