Will you be a lover, a traitor, a spy, or an ally? Sunset takes place in, "a luxurious penthouse apartment against the backdrop of violent revolution in a fictional South American metropolis." As a housekeeper, you get to snoop, and in snooping you start to discover things that draw you into "a rebellious plot against a notorious dictator Generalísimo Ricardo Miraflores."
The 70's as a decade should probably be explored more in games. So too should the idea of not being the man with the gun, but a regular person amid the turmoil. Of course, the whole point of Sunset is that you still have influence, and whether you choose to use it or not, and how, is going to color the story.
Oh, and Austin Wintory (Journey, Banner Saga) is doing the music. Lovely.
