EDGE: "Games aren’t movies. They’re theatre. Each one an in-the-round performance with room for improvisation and that encourages audience participation. There’s a theatrical maxim that goes by the name of Chekov’s Gun, and what it boils down to is that if a rifle is hung on the wall of a set in the first act of a play, it must be taken down and fired in the second. It ties in to both efficient, lean design with no surplus ornamentation, and the old adage that you should show rather than tell. Games do this all the time, as you perhaps watch enemy soldiers in an FPS using heavy weapons you’ll surely be using against them later, or more specifically in BioShock Infinite when you meet the Handy Man at the fair."
