Would an RPG where you get to choose between being a good, clean detective or an evil bounty hunter work? You could choose to find people via clues and tracking their movements or asking/interogating/torturing people for answers. You could work for the police authorities or the mob or some gang. You'd also be able to collect/steal/buy investegator gear. There would have to be real attention and detail put towards the storyline for a game like this to work maybe? What do you think?
