This is actually the last game I played that made me wonder how far down the rabbit hole a person would want to go.A good Example for a Game like this would be Raptus.You can choose to strangle/murder but you dont have to so this would be the best option when it comes to decesions.
I personally like Games darker than the Basement where they are stand in the pillory
12/10
To me, dark isn't just gore and taboos, but a story of playing a person who thinks like the guy in Raptus.
Also just recently finished Mindhunter (tv show) and I'm thinking: what if you take the premise of Dexter, wrap a good story around it, but give the player the option of slowly turning into Dahmer?
