I have a book I am working on that I have been told has to many characters but, in my opinion all of them are needed. Now when I say to many characters I don't mean there all Main characters most of them are maybe only mentioned only a handful are actually seen. They are there in my story to flesh out the world. In total there are 50 something minor and major characters. I was just wondering is that to many? Should I try to cut the number even if it means sacrificing a feeling of a rich world? I mean most if not all have there purpose for being mentioned ,but can there be such a thing as to many background characters?
