Just because it exists doesn't mean you have to read it, or appreciate it. But I would encourage people to accept that it does exists and that people do derive a form of enjoyment from it, and as long as they aren't violating any laws by trying to profit from it, then leave them be.
I see what you're saying, and I agree with you to a point. I do the same RPG stuff you do, so believe me I get where you're coming from there. I think our opinions differ a bit in that I think there is some difference between RPG fic, which is based on a game that actively encourages people to make up their own stories in the game setting, and fanfic that's based on something that doesn't have a RPG. For example, a Dresden Files RPG group might publish their stories in a LiveJournal community for fun and amusement, and I don't think that Evil Hat would have a problem with that as long as game mechanics aren't published. That's what the game system is there for, after all. A series of Codex Alera stories, however, would be different because it's not meant to be used the same way a game system is meant to be used.
So, with that said, I do admit I play around in the sandboxes of others, RPG and otherwise, because it is very much fun. No argument there at all. The only thing is, I don't publish it because I don't want to cause problems for the authors. I have two major reasons. Of course if it's an RPG, the rules are bendable:
I want to support my fandom. I don't read the work of other people or publish my own, because there's already works out there by the original author. That's the main focus, and that's how it should be.
Allowing fanfic makes it okay for others to make this particular work their own. If the author leaves it alone, then when he does need to defend his copyright in court the fact that he didn't zealously protect the intellectual copyright
here makes it more difficult to justify to a judge the defense of intellectual copyright
there. It's already hard enough to defend copyright without leaving any room for weakness in the argument.
I'm not calling fanfic writers bad people, and I'm not saying they can't be as creative or insightful as any other writer when the talent is there. I just think that we need to keep a sense of perspective and remember, it's not ours. We can talk about it, obsess over it, create multiple threads, dream up alternate stories, and discuss the villain's hair color at length but at the end of the day it belongs to the original person who thought of it, put in the massive hours of work to bring it to the public, and deserves the recognition.
In other news, run-on sentences are my bestest of friends.
