My best friend and I where discussing DFRP yesterday and he voiced a concern to me that I find very hard to place. And I'm wondering if anyone else might have encountered this phenomenon. And if so, what kind of effect has it had on your game and how did you deal with it?
The idea my friend has is that because you're playing a game based on these novels an inherent expectancy will exist with your players that these novels will have a direct impact on whatever you run in your games and vice versa, what the PC's do in a game can have a profound effect on the novels.
Also that you're playing in a world where there are all these heroes like Harry, Karrin, Bob, Michael, Mab, Titania etc. And that creates the expectation that you will interact with these characters at some point because the world is very small. Though it's harder for wizards with the Murphy effect you can get to nearly any place in the world within a day. So even if you set your game somewhere away from Chicago, the players can decide to pack up shop and move in to some of the appartments above Harry's own.
He thinks, this will inevitably lead to dissapointment among the players. Because once you start making your own ripples in the world you're going to change the setting so much that the original timeline of events no longer make sense. IE: During the war with the Red Court Mab bites the bullet so Harry won't become the winter knight but instead has to take up the coin or perform the darkhallow somehow.
Or when you're running the 'iconic' characters of the game as the GM the way you portray them will never be 'right' compared to how they act because of various reasons, mainly that the GM isn't going to be Jim Butcher and (s)he'll portray the characters colored by his or her own perceptions and ideas.
He figured that the only way to avoid these dissapointments would be to set the game in such a way that it would be impossible for us to meet any of these iconic characters by moving the time during which the game takes place forward or backwards in time to a point where Harry and his gang haven't been born yet or are already dead.
Though I can see his standpoint from an academic view point. I can't see it actually happening that these effects or feelings would ruin a game. Unless these iconics are used in such a ham-fisted way that displays them as 'the awesome guys you can never be'.
