Dark Souls is pretty different from Skyrim gameplay-wise, but having achieved 1000/1000 in both titles, I found Dark Souls to be a much more rewarding and thrilling experience. But hey, the game isn't for everyone.
My favourite part of Skyrim was exploring with the relaxing music. Man, that was cool. Everything else was kind of a chore. But you know, apples, oranges, different strokes, creative work is of course all very subjective etc etc etc
I am looking forward to checking out this DLC at the end of the day.
