I got the game from steam sale and playing it now. I am still in the starter area (broken valley). From what I see, the demo seem to have been updated to match the game since so far they are playing out exactly the same.

I have only put in about an hour or two into DKS and I seem to be enjoying this lot more than ME2 (i played for it about 10 hours). Good story, decent combat and good RPG system (lacking in ME2).
