Sacred Haven of Debauchery

Where did you get stuck?
I replayed it a couple of times, and I always have problems with the investigation in the Temple Quarter...

I got stuck on the third act, because the problems are again related to my stubborn video card :(
Regarding Dragon Age:
Vesk:
well, I wouldn't say that the NPCs are boring: for example, one elf was very persistent in pursuing Zubr, who was playing as a noble elf, but he was rejected because Zubr chose a lady.
