I often have this problem. I try to think on new characters to fill a numerical need of mine stemming from my OCD. I am trying to address it as I have read various articles saying that larger casts for leading roles often cause to not being able to link in with them. Quite usually at the lead of my story is some team, some union of characters. In the one I am currently working on there is a group of four characters who have been brought together, from a young age mind you, but they have been brought together to fill a certain role in the universe of my story. I think four is an okay amount for the leading characters. it's a nice rounded number. these characters get separated or separate I'm not sure which direction to go with that yet but they split up. I now find myself adding more characters. they are not main characters but more so to give interaction with the leading roles. Is there a common point you guys think of to just say woe woe woe I need to do more with what I have rather than add more or do you think that a story can stand with a large cast and still have the audience not being thrown around from person to person. I have seen time and time again instances where characters are half haphazardly thrown in to fit a point or because they'll be important later so hey let's get you here now. Also, what do you think makes a character more.... emotionally connected to the audience I'm planning to have a love interest die at a much later point in the story and I do not want her to simply be someone we saw and now she's gone. I want it to really hit the audience.
