Game Idea... Maybe?

So I think I came up with an idea for a game. I want a horror game that for the first few levels will profile exactly how you play and learn more about you and who you are. After the game has this knowledge about you it will customise itself to be as scary as it can be with the way you play. Also if you stop playing the game and someone takes over it will realise that a new player is playing and change the knowledge that it has on you to gain knowledge about the next person who would be playing. Although it would not know that a player has changed it will sense a change in the way that the game is played.
Eventually to the game I would like to add a webcam feature to the game that will monitor your face and body for anticipation. When the webcam senses you are at your calmest something may or may not happen depending on the way you play the game.
To stop people from faking the webcam experience with a computer program there will have to be a program detection within the game that will detect when a program is being used with the webcam at the same time.
To create a game like this I will need to have a good understanding of the psychology of fear and anticipation to make the game the best experience it could possibly be for you. The game would have to have an intelligent agent feature so that it can keep learning about you which will probably take the most time.
When and if I create the prototype of this game my focus will not be completely on the graphics of the game but more on the intelligence that the game will have. Although if this became a mainstream game it would need constant maintenance as fears and anticipation could be ever changing and people might be able to find a way to get around the system so it must be as secure an experience it can possibly be.
