As someone who writes a little as a hobby, this is something that I haven't really thought about until just recently, but...
Is it common for a writer to develop characters before actually coming up with a plot for those characters to be a part of? That is, do most writers start by coming up with a story first, then creating and developing the characters to be used in the story, or is it more common that a writer will get an idea for a character or characters and will then develop a story to use them in?
I'm asking this because I noticed that, in almost all cases, I've had the idea for a character or characters first before I started actually writing anything about them, and I was wondering if there's a trend among writers about which tends to be done first. Could this simply be a side-effect of having a taste for world-building? I've dabbled in aspects of world-building in the past, even going as far as working on a constructed language for use in a story, but I'm not sure if the two are specifically related.
Also, I tend to be more detail-oriented in things as opposed to looking at the big picture; could that be part of it as well? I've noticed that once I have the characters and a (rough) setting, I often spend time on coming up with specific scenes of interaction rather than an overall plot.
