Has a Black Mirror episode predicted the future of video games?

In Playtest, a developer creates an augmented reality horror adventure that uses the player's own memories to scare them. This is closer to reality than you may think

The latest Black Mirror series from Charlie Brooker presents, despite its transition to Netflix, another unsettling collection of future shock nightmares drawn from consumer technology and social media trends. The second episode, Playtest, has an American tourist lured to a British game development studio to test a new augmented-reality horror game that engages directly with each player's brain via a biorobotic implant. The AI program mines the character's darkest fears and manifests them into the real-world as photorealistic graphics. Inevitably, terror and mental breakdown follow.

The idea of a video game that can analyse a player's personality and change accordingly may seem like the stuff of outlandish sci-fi to some Black Mirror viewers.
