My point is it's not even really a spoiler. A spoiler would be like knowing the ending of a game. Which would bother me as much as if someone told me the ending to a movie before I watched it. But knowing there is werewolf's in it being considered a spoiler is silly.
Well, technically as Bethesda denied that they were in the game, they must have wanted it to be a surprise. Having played up to and past the point they are revealed, the way it is done is very surprising and had I not known about it, it would have been a lot better, it was still awesome, but you know what i'm getting at.
So yeah, I would consider it a spoiler for some people.
