Granted, I have to say this, the level designers have a bit of a "mean side" that sometimes surfaces in the game. A reviewer did notice this as "the player fighting against the level designer."
That aside, I can say with experience that Nightmare Mode in DKS is nowhere near the sadistic Hell mode in Diablo II (1.12 patch and up IIRC)
There is a sort of "fiendishness" in the game design but I did not detect the same "mischievous" air with nightmare mode.
