Helpful information and Questions to consider
Format: Paperback
As a writer of science fiction and fantasy I had already looked into the physical aspects of the worlds I was creating, but I quickly realized I needed to include society and culture in the worldbuilding. I started a search for information, questionairres, or guidelines to use and found very little that would be helpful to me as a writer. Until I came across this book. It's exactly what I needed. It touches on multiple aspects of beliefs and practices and asks questions to help you think through what you want for your worlds, even if it's mostly backgroud. A very useful tool.
