Jesus, alright, Dragon Age is the darker one. My bad. Are we good? 
And concerning my previous post regarding the whole "it's more supernatural here than on that game" I just meant the plot. Witcher was about civil war and neutrality while Witcher 2 was about regicide and war. The whole magical aspect revolves around a central storyline that is not inherently "fantasy". Except maybe the whole Wild Hunt bit.
How about neither is the "darker one?" Why do we need to rate them? Let's leave it at that.
I would argue the same--that the storylines of DA have not been inherently fantasy either. DA:O was the Blight (as well as civil war). While one could argue that it's fantasy, I would say that at it's core it's not about the "fantasy" or the darkspawn, or any horror elements, but simply about a war. That's not fantasy at all.
And DA ][ was the story of Hawke. Act 1 wasn't fantasy--Hawke goes on expedition for artifacts, which he/she sells and becomes rich. Act 2, the Qunari decide to take over. Act 3, mages and Templars--you have a point with the mages, though the themes are simply individualism versus community, which isn't fantasy.
I'm saying let's not build this "the Witcher does everything that Dragon Age doesn't" claim because it's silly, a little petty, and can easily be argued.
You see personally for me it's the other way round. That kind of signposting leeches the impact away for me. If I come to a slow realisation that you know, despite the fact everyone is getting on with life there is nonetheless a pretty horrific set of circumstances at play, it' more effective. If the story saves the obvious drama for one or two big set pieces fine, if it's shouting 'Look! Bad stuff!' every other page it's a bit wearing. Your mileage may of course vary.
For what it's worth, I'm kind of the same--all the children singing these absurdly dark songs in these absurdly carefree singsong voices in TW1 didn't make me think, "wow this is a serious world," it made me think, "wow you're trying waaay too hard, CDPR."
Edit: And for what it's worth, I felt the same with the orphanage in the Elven Alienage in DA:O. That quest had some dark parts, but the kid saying "One, two, Maric's run through" felt cheesy.
