The Crow could make for an awesome RPG experience.

It really deserves the Disco Elysium treatment. Yeah, the eponymous anti-hero gets his kill on throughout the whole story, and that's tempting to build a game out of; standard revenge plot stuff. That said, there's way more on offer here. How about a detective story that follows a murderer that's already dead? Or, maybe you start off not knowing you're dead and puzzle that together as you go. Or perhaps you're constantly crossing paths with said detective, solving your own mystery, always a step behind the shadow of your dead friend?
