Catherine’s done well for Atlus in North America. According to a tweet from the Atlus USA Twitter account, the game sold 200,000 copies in its first week following its release. Atlus celebrated the occasion with a cake:
Catherine also exceeded Atlus’ sales expectations in Japan. Atlus were expecting 150,000 copies in Japanese sales, and the game went on to sell 250,000 units by the end of February, which led to an increased goal of 300,000. Parent company, Index Holdings, then announced plans to expand Catherine as a new franchise.
