For me, it doesn't matter anyway. I personally don't rank "originality" very high on my list of qualities that make a good computer game. At least not as far as story or characters or world-building goes. Or even graphics so much. In gameplay, yes, there its nice to see something new, or at least something spun around and done slightly differently, at least occaisonally. If DA rips of Tolkien, its ok with me. If I don't like the game, that won't be the reason why.
I agree completely. In fact, I will go further and say that a game being 'original' just for the sake of being different will often turn me off the game - for example, I haven't played the Witcher. I like my fantasy conventions.
