From the PlanetXbox360.com feature hands-on preview:
"Atlus is the type of developer that doesn’t count on their titles to sell a million copies - but they’re fantastic at carving out niches that the hardcore revel in. They're doing it once again by bringing the ultra-seductive game Catherine stateside. Atlus’ focus in Catherine is the inner workings of relationships, as Catherine explores the begging question that many guys will ponder in their life: Is it time to settle down? The game is structured using puzzles and choice to provide not only exploration, but also commentary on relationships. Fidelity is a key aspect of the game, as the main character, Vincent, has just been issued an ultimatum by his girlfriend Katherine: fully commit to her or else."
