I got The Darkness from Gamestop for five bucks. Because I had one of those point-coupon things, I got the game for free.
And when I played it, I experienced something I had never felt before: The Darkness made me care about an NPC. Not because she was relevant to the plot, or it was an escort mission, we were just cuddled up on a couch, watching To Kill A Mockingbird, and she kissed me. Well, my character. It was immersive.
By contrast, the only reason I chose the family end in Fable 2 was to get my dog back.
