Character driven plots are even more delicious when there are loads and loads of characters, because it can get so complex without it being forced. That's one of the reasons I like A Song of Ice and Fire so much, because it's just so fun.
I'd think point two is the most violated, at least in stuff I've read. Most of the time, I just say "Why do you care, you altruistic nitwit!" Maybe I'm just selfish, but most fantasy protagonists are too nice to be real.
Quick question: I'm having a block around showing a particularly mental-oriented character's thought processes without internal monologuing. Do you have any tips?
