you are not forced to become a werwolf or nightingale.
Yeah. I was very satisfied with my Fighters' Guild experience. First mission: I went to kill a raccoon the next town over. Second mission: sorry, you don't get a second mission unless you pledge your eternal soul to a murderous godling and let him turn you into a giant dog.
Oh well, I guess I can walk around at random and fight bears and pretend I'm doing it for a reason. Cool! My warrior character is fully realized. What a great story!
As for the Nightingales, the less said about that the better. Though I will say that I was overjoyed with the numerous options there too. (1) Out of the blue, dress up like a reject from a Batman fanfic and (again) pledge your eternal soul to some chick in exchange for, uh, I don't know, 25¢ and a punch in the mouth; (2) Close your eyes and run away from the story that's been building up for the last 15 hours. Optional: stick your fingers in your ears and go LA LA LA LA LA
Seriously, some (not all, but some) of the writing and quest structure in this game is sheer garbage. "Do this quest in one incredibly contrived and stupid way or don't do it at all" is not freedom of choice.
