3. Sin City
Sin City is already a place full of dangers and hardboiled men making hardboiled choices. It's a hard world for the denizens of the titular city with plenty of open space to play. Frank Miller's comic books are already famous for having characters pop in and out of each other's stories, so this is a golden opportunity to create a new protagonist and slide him into this gritty noir. We could come at odds with Marv, get a lap dance from Nancy Callahan, becoming entangled in Dwight's hard fight. It's an open world for Telltale to roam in and seems almost too perfect.
