The Catherine site has some interactive elements too, prompting a user with a question to even enter: “Can love exist without pain?” Your potential answers of “Of course!” and “No way man!” take you to slightly different versions of the site, focused on either Catherine or Katherine depending on your answer. There’s also an interactive text feature that allows you to send texts back and forth to Catherine. The site mentions to check back every day for new messages and replies from her, which again rely on choices you make, which is enough for me to be going back to the site tomorrow.
If the text feature and the first question when you first go to the site are any indicators, Catherine’s story progression is most likely going to be open and heavily dictated by choice. And if Atlus as a developer is any indicator, those choices won’t always be a basic yes/no, but probably more philosophical in nature, bordering on “what would you do” types of scenarios. Based on the art and trailers, the animation seems like it is a good balance between anime and full CG, and the music sets an appropriate dark, seductive tone for the story’s backdrop.
The game was apparently a hit when it was released back in February in Japan, so we’ll see how it does here in the US. It certainly looks like it's something different and a good change of pace from the other games that are out there. It’s available for preorder now in three forms: the standard edition, the alternate box art if you're afraid you'll be ashamed of having it on your shelf, and the “Love is Over” deluxe edition should your tastes require some additional saucy goods. The game will officially release in the US on July 26, and it should be a good time. Catherine even texted me to say so.
