The first time we played Fog of Love, my favorite new board game of 2017, the game was careful to remind my wife and me, over and over again, “This is fiction. This isn’t real.” We quickly sussed out what it meant: This isn’t really you. Nevertheless, there we were. I played a successful TV chef who clicked with my wife’s character, an ambitious young politician, at a party. Soon, we were in a relationship, trying to balance our goals for togetherness against our own goals as individuals.
