...Yeah. I took the term power creep from him. He often says that the way for an author to handle it is by having to know where your character is going. It's stated in conjunction with a story has a beginning, a middle, and an end.
To be fair I think the term "Power Creep" is usually taken to mean how characters slowly become to powerfull for the obstacles they are facing. Like in DnD at lvl 5 the world is full of deadly threats, but at lvl 15 a good party can really steamroll a lot of things. Jim then states that he is not going to have this problem in Dresden Files because he has planned out the books till the end. In this way Dresdens power will never creep too high relative to the things he is fighting, i.e. there will be no power creep.
I agree, but I really like the thread so I just took the thread to mean Power Increase, which I think was Bad Alias intent.
Moving on.
One thing I like related to power creep is the realization that comes from meeting something that used to be a threat, but is not (much of a threat) anymore. Like in a DnD game where we early in the story had a boss fight with a troll and somewhat later had to conquer a small castle manned by lots and lots of trolls. That made the progression of our characters very clear. I hope we will see that in Peace Talks, e.g. Dresden punching an Octokong in the face.
