TYVM both! I expected disclaimers were a given, just wasn't sure if they'd cover dialogue too.
Well, if you're really worried about copyright, then you shouldn't be playing in their sandbox at all with fanfic. BW is only concerned (in practice!), potentially, if you start selling stuff with their IP. And folks still even do that.
My philosophy has always been that so long as you're respectful, generally, you'll probably be ok.
I am not sure what the "rule" is, except to be sure that you state that all chrcaters belong to bioware in the your description. For reading, I personally enjoy a bit of both in there. When the scene is just bioware lines, it can boring. When you mix some new lines, etc, it makes it more interesting. I personally like to play with the lines...like, if there is a line I love from Cullen in the game, l plug that line in a different context as a shout out to the original writers. Imagine all the different scenarios where Cullen can say "I'll keep that in mind". I think it is a compliment to the writers, not plagarism...but I could be wrong...
I think it's new even if you draw the dialogue from a scene verbatim. An ingame script and a fully written scene still can be quite different.
In any event, I would just tell the story you want to tell, and it's already drawing from the Dragon Age IP even without direct quotes. :shrug:
