#WritersCoffeeClub - 6 Oct. What size casts do you tend towards? Why?
I prefer in-depth characterization, which militates against having a cast of thousands—unless I'm writing a large multibook series (like the Merchant Princes or Laundry Files).
Large casts are easier to portray if you have a contemporary/historical setting that doesn't require lots of worldbuilding. (In SF/F, the world is a character.) There's a reason why big cast far future SF usually has thin characterisation.
