Games within games in Gone Home

While rummaging through the closet of my parents’ house back in 1995, I came across this boardgame. I want to play it. Unfortunately, it says 2-6 players and no one is home. Where is everyone? Where is my sister? And what’s with the the elliptical references to time travel, sci-fi, insanity, and dark family secrets? What is Steve Gaynor, the writer of the Minerva’s Den DLC for Bioshock 2, setting me up for in Gone Home, a darkly atmospheric first person exploration game developed by a small team in Portland and available later this week?
