You meet six other dads who just happen to live in the same suburban cul-de-sac, and with a little help from a Facebook analogue called Dadbook, the dating begins. Although the two of you have been on your own for a while, the death of your spouse-you can specify if they were male or female-clearly still weighs on your mind. The game casts you in the role of a single father who has just moved to a new town with his teenage daughter.

You don't just date dads in Dream Daddy, though you are one. Not bad for a tiny game, created by two people, that upends so many notions about what works in a game-and about gamers themselves.

A month ago, if most people had tried to predict what kind of videogame would become the game of the summer, very few of them would have guessed 'queer dating simulator.' Yet, Dream Daddy did just that, with a pair of stunning usurpals: Not only did it replace beloved first-person shooter Overwatch as the most-discussed videogame on Tumblr for the first time in more than nine months, but it shot to the top of Steam's global sales chart, unseating battle-royal phenomenon PlayerUnknown’s Battlegrounds.
