Catherine is a game that is not without its flaws, and at first glance, it seems like an odd choice for a list like this. It's primarily a single-player game with a small multiplayer offering that follows the story of a less-than-ideal romantic partner and his issues with commitment. That said, the game does close out every chapter with a moral question about relationships and that can be fun to talk about with your partner as you watch the train wreck unfold. Of course, this is assuming you answer the questions correctly. Once you answer the question, you then get to see how other players answered the question on their first playthrough. It's an interesting way to see how people view relationships. The game constantly asks the players to think about what they think is important in a relationship.
