Having just been released, and reviewing quite well, Catherine is reportedly the largest launch that Atlus has had for a game yet.
"Catherine has exceeded our highest expectations," Tim Pivnicny, VP of Sales and Marketing at Atlus, told IGN. "It released last week to tremendous critical acclaim and fan response, bolstered by the release of a demo a couple weeks prior, and continues to generate discussion among fans for its mature themes, engrossing subject matter, and frantic, challenging gameplay."
"It is fitting, then, that Catherine can boast the largest launch in the 20-year history of Atlus, and continues to see strong sales at retail."
Exact sales numbers were not given, but I’m sure we’ll hear about Catherine reaching the landmark ‘1 million sold’ soon.
