Immersive reality

From Tardis Wiki, the free Doctor Who reference

Immersive reality games were a type of video game created on and popularised by the Sphere of Freedom. The planet exported the games to over a thousand star systems, with an estimated player base of at least several billion. They allowed players to feel as if they were inside the game itself. (AUDIO: Sphere of Freedom)

The most expensive and high-end immersive reality game was Fugitives. In reality, this game was being powered by time eddies moving people into different times and places for a more realistic experience. Audrey Mohinson used this both to generate money for research and development and to feed the resulting space-time shadows to the Ravagers, using the feelings of fear generated to prevent them from destroying the universe. (AUDIO: Food Fight)

The Ninth Doctor loved immersive reality games, especially Geraldo's World. Nova, however, was not a fan despite working on the Sphere of Freedom, due to only accessing cheap games as part of her pay. (AUDIO: Sphere of Freedom)
