1UP: The world of Catherine teaches us many things: don't cheat on your girlfriend, be honest, and always prioritize running away from murderous tongue monsters. But what does it really teach us about relationships? The long-term girlfriend Katherine and sexy seductress Catherine each provide main character Vincent with a number of moral decisions that affect his standing with both girls. We've adapted these life lessons of Atlus' new game into advice you can easily integrate into your own dating life, or lack thereof.
