I don't know what "fable s***" is, but I agree the games listed in the post may imply the survey isn't especially relevant to NWN. Then again, plenty of discussion on these boards centers on topics that are very clearly related to the OP's topic, such as whether alignment is or should be relevant in NWN modules and PWs, whether quests with a moral component are of interest to players, etc. I'm not looking to rehash those discussions, but just to illustrate that, to the extent the OP is off-topic, it's primarily because the mentioned games do not include NWN, not because ethics and morality in video games isn't of interest to NWN players and content creators.
On the other hand, one might claim the post is a form of spam in asking forum members to check out your academic study on gaming, but that's another grey area. Lots of people link to their PW, or gaming blog, or whatever. and no one seems especially fussed about it. The OP's topic clearly not the kind of outright commercial spam such as we saw a few days ago from freemovie24.
