What appears through the entire story to be monogamy-in-progress ends up in polyamory, so if that throws cold water on you (as it did for me), may want to avoid playing this one, or at least not complete the final fight scene at the antenna. It's literally the last slide/scene of the game that ruins the rest of it if, like me, you're monogramous.
