Gone Home is a walking simulator -- a really good walking simulator. While Gone Home may not transcend the genre the same way The Stanley Parable might, it's definitely much more representative of it.
Playing the role of Kaitlin Greenbriar, the player will return home from a semester abroad in Europe, only to find the house empty. The player will have to explore the house in search of clues that'll help them figure out where the rest of Katie's family is, which more or less constitutes the entirety of Gone Home's gameplay.
Gone Home isn't exactly the most groundbreaking game ever, but it's short, it's sweet, and it's got a great story and atmosphere. You can't really go wrong with that. (Although you might want to pick the game up at a discount if you don't think two hours of entertainment is worth $15.)
