"Hi honey, what's on TV tonight?"

*Rail Gun*

I once saw a short film that was pretty much like that. The characters lived in an alternate video game universe in which daily life involved the usual violence of a FPS and dodging death in various forms. The main character was a boy who was playing a video game in which he had to be nice in order to succeed (e.g. helping an old lady across the street instead of shooting her).

I won't give away the ending. I can't remember the title of the film but it was made in England.
