Sounds interesting. So how would the role-playing work? In other words, what is the role of we, the players and our characters? I suggest that you spend a bit of time fleshing out the city itself, perhaps explain it's social classes etc. What genre would you place this? Is it action? Drama? Drama and Suspense? Will it play out as a bit of a crime thriller? The concepts interesting; I just don't know what to expect from it.
