Haven't played - but I wonder if it is related to the Hawk and Fisher series by Simon Green?
Basically they are two tough honest no nonsense cops in a very corrupt city, Haven, in a medieval, magical, world. Entertaining books - basically six novellas with the same characters and some overlap.
Haven read like a larger version of Sanctuary - if Sanctuary had even more organized crime, and polically based corruption and crime, it would be Haven.
