How many copies had The Origami King sold by September 2020?

Paper Mario: The Origami King had sold about three million copies by September 2020.

Nintendo released The Origami King for Nintendo Switch on July 17, 2020. Within roughly two and a half months, it had become the fastest-selling game in the Paper Mario series, helped by the Switch’s large worldwide audience and strong demand for first-party games during the pandemic period.

The figure is commonly rounded to three million. Nintendo’s financial report covering the six months ending September 30, 2020, recorded 2.82 million units, while later reporting gave 3.05 million by December 31. Thus, “three million” is the fair quiz answer, even though the precise September accounting figure was slightly below it.

The game also stood out commercially because it exceeded the launch performance of earlier Paper Mario entries. Its sales success did not remove debate about its design: critics praised its writing, music, visuals, and inventive ring-based battles, while some longtime fans missed the deeper role-playing systems of the first games.
