Matt Casamassina revealed that the game would be released on August 20 in the United States. Nintendo of America later announced to have moved the release date to August 27, but Nintendo finally revealed an "in stores" date of August 28. The game was later released in Europe on October 26, and in Japan on March 6, 2008. In the Japanese version, the game's difficulty level is decided by answering to "a questionnaire from the Galactic Federation", in contrast to the North American version where the difficulty level is chosen directly by the player. Metroid Prime series producer Kensuke Tanabe said that an idea for a questionnaire came from Retro Studios. Casamassina initially criticized Nintendo for its minimal marketing campaign for Corruption and compared it to the larger campaign for the original Metroid Prime, which included its own live action advertisement. He concluded that the campaign was the result of Nintendo's new focus on casual games for their console. When questioned on the company's actions, Nintendo of America responded: "Nintendo fans will be surprised by the quantity and quality of Metroid Prime 3: Corruption information that becomes available before the game launches on Aug. 27. Your patience will be rewarded (or Corrupted)". Following this promise, Nintendo released the "Metroid Prime 3 Preview" channel on August 10 in North America and on October 15 in Europe. The channel, available as a free download via the Wii Shop Channel, allowed Wii owners to view preview videos of the game that included a battle sequence and previously unannounced details on new characters. The Preview channel was the first in a series of new downloadable content including videos made available in North America. The "month of Metroid", as named by Nintendo, included Virtual Console versions of Metroid, available on August 13, and Super Metroid, available on August 20. Rerelease Metroid Prime 3 was rereleased on August 24, 2009 in North America and Europe, alongside Metroid Prime and Metroid Prime 2: Echoes, as a single-disc compilation, Metroid Prime: Trilogy. Prime and Echoes feature the motion controls and achievement systems introduced in Corruption. The compilation was later rereleased on the Wii U's Nintendo eShop on January 29, 2015. Reception Metroid Prime 3: Corruption received critical acclaim. Nintendo Power praised the visuals and the immersive gameplay, calling it one the best Wii games. IGN awarded it the Editor's Choice Award, and noted that the game was beautifully
