10 Dark Doctor Who Facts That Are Never Spoken About

10. Video Game Characters Can Feel Their Deaths

Gaming is one of the most popular hobbies in the world. The Doctor has played a little bit themselves in the past, memorably enjoying a spot of Wii tennis while investigating the Shakri cubes in The Power of Three.

Wii tennis aside, most video games involve blasting away wave after wave of virtual enemies. However, it turns out that the people you're mowing down aren't just pixels on a screen.

Series 10's Extremis finds the Twelfth Doctor dealing with a book called the Veritas, which causes anyone who reads it to commit suicide.

This ends up with everyone realising they're in a simulation, and as the Doctor attempts to explain this to Bill, he talks about how they can still feel real even while living inside a computer. He tells her, "Those pretend people you shoot at in computer games... they think they're real. They feel it."

The Doctor often says unusual things in jest, but this is such a serious moment that there's no doubt he's telling the truth. It means that every Goomba stomped in Mario, every soldier gunned down in Call of Duty, every ghost eaten in Pac-Man... they felt every single bit of it.

It'll certainly make you think twice while playing through a Doctor Who video game yourself.
