I like Runied's idea about the serial killer but to expand on that what about letting you inside the killers mind like in that movie the Cell. So then you could have a really gritty real world setting plus the twisted mind of a serial killer to travel through. When your in the mind of the killer you could battle his personal demons and have cut sceens to show why this man is who he is. It could be one sick game.
