Hi. So, I have been trying to set up two, potentially three WIP's and while I do have an idea of the kind of themes I want to write about, and what sort of setting, I am uncertain about the world building. My preference is writing in the Fantasy genre, with a contemporary setting. What I am uncertain of is, if I work on two different WIP's now, how distinctive can they be when it comes to the world the characters live in? I have been considering a different genre, I do like Crime/Detective and Science Fiction but I don't have specific ideas for any of it as of now. I know there have been authors who have used the same world building but different characters in different books, but I don't think there is much of a point when I probably will stick to a modern setting in both my WIP's. I am not sure what to do, how to solve this issue? Do I start with my characters and my themes and then create the world around them? Or...?
