I loved this game. I always cycle between two or three games - a AAA title for me, a casual game for lunch at work, and a co-op game to play with my wife. I played Unpacking when it came out, and had such a blast with it. The audio in particular is astoundingly well done; I put so many things in the wrong spots solely to hear all of the different sounds when you put stuff down.
There are also so many little secrets buried in the game, so many ways to arrange. You end up with a story you’ve told yourself about the life of this person via their stuff, but if you compare notes with a friend who’s played, your story may be very different. I love that it’s so open to interpretation.
