Prope began operations on June 1, 2006.
Ten members of Sega's Sonic Team joined Naka at Prope, with a starting capital of 10 million yen, 10% of which came from Sega in exchange for the right of first refusal option for publishing games made at Prope, though if Sega rejects a title produced by the new studio, Naka would then be free to approach other publishers.
Previously, the studio had been consistently linked with a sequel to Nights into Dreams..., though Nights: Journey of Dreams was ultimately developed by Sega Studio USA. Naka has claimed in an interview that he presently has no intention to revisit any of his former Sega properties.
