...

Not really**, although I've read/skimmed far less DA fanfic that I have read in other fandoms.

I'm certain such stories exist there and I just haven't found it. I've heard of a few DA stories that fall into this specific kind of metafiction but I haven't read them and have mostly just heard tidbits in passing so I don't have links. It's just another case of DA fandom feeling (at least to me) a good bit different from prior fandoms I've been in.

I'd love to find fan fiction that blatantly explores Kirkwall and DA2's in an intertextually/interdiscursively aware manner, where the story is, at one level, just a story, but at another level the story is commentary about Thedas, be it any of the following:
1. Parodical exposés of where bioware's writers went down a problematic path.
2. Deep meta that makes a serious attempt at unpacking how societies in Thedas might really work based on the canon given to us.
3. Further deconstruction of how DA2+Hawke's story is a deconstruction of heroic fantasy.

[** discounting some projects I and a co-conspirator are quietly working on, both together and separately]

Most of the Kirkwall-based DA2 fic I find is fluff for the sake of fluff, romance for the sake of romance, or erotica/smut/porn/kink. The longer stories that follow a plot tend to be pretty good but ... they feel more like borrowed character fanfic than canon-exploration fanfic.

I sometimes wonder if the controversy and difficulty in DA2's canon scare people off from exploring it.
