I’ve seen countless people who are interest in Catherine express their sorrow about no EU release. Atlus isn’t the bad guy here. According to a response from Atlus’s PR and sales manager Aram Jabbari, Atlus just needs a EU publisher to help them spread Catherine out to the PAL regions.
I wouldn’t worry too much about it, EU readers. Catherine did really well in Japan, and American critics seem to love it as well. Once the reception for the title is out there, I’m sure a European publisher will pick up the game in quick haste. Right now, it seems to be just a matter of waiting. Hang in there; Catherine looks to be worth it.
