"Catherine can boast the largest launch in the 20-year history of Atlus," Atlas VP of sales and marketing Tim Pivnicny told IGN in a statement this week. Though he did not reveal any sales numbers for the eccentric, adult-oriented puzzle game, he added that "Catherine has exceeded our highest expectations."

The game launched in North America on July 26 for the Xbox 360 and PlayStation 3, apparently garnering enough attention pre-release to post record-breaking sales numbers. Without any numbers provided by Atlus, it's hard to gauge just how well Catherine is doing, but the NPD results should help elucidate the matter within a few weeks.
