Influence

 Fallout: New Vegas is a post-nuclear apocalyptic video-game set in 2281, in the Mojave. Playing as the main character, the game begins with you being shot and buried... but a robot saves you. On a quest to find who and why you were put in such a dangerous situation (your memory is mostly gone as you took a shot to the head), you eventually find yourself in the city of New Vegas. 

As you uncover secrets of the city, you find out a mysterious “Mr. House” is responsible for saving the city from nuclear attack hundreds of years ago, and now is behind the scenes of everything that happens there. Somehow, he has reached a near-immortal state. We never get to see his body, only a face on a screen very much resembling big brother.

The reason I was reminded of Mr. House when reading 1984, is because you are eventually faced with the decision on who to entrust the fate of the Mojave to. Mr. House runs New Vegas through an oppressive system, but nobody feels like they are being oppressed. Like in 1984, Mr. House monitors everything in New Vegas. He constantly asks for your help and trusts his own future survival to you. Basically, you are asked to decide whether to continue a 1984-like city, claim it for your own as independent (backstabbing Mr. House), or let an outside army annex it. If only the situation in 1984 could be influenced by a single person.
