Since there have been so many discussions on character development (male, female, or otherwise) I wanted to start a discussion (just a discussion here, no promises implied) about what it is that you find the most compelling or interesting about a character? What is it that makes a strong female character strong, or a male character the right kind of vulnerable? What is "enough" for the development of a character?
Everyone has their different perspectives and rather than an argument about what people don't like, I thought it would be productive to find out a bit more about what it is you like.
(Examples are always welcome as well.)
*As always, please keep it clean and refrain from any personal attacks or inappropriate discussion. Please avoid flame bait points of discussion. ie. If you know it usually ends badly, please try to be aware of that.
I think this is an apt discussion for Diablo 3, as many seem to have been disappointed with the story and its execution. What are some things you liked in a story and its characters?
