Cancelled Crash Twinsanity GameCube port
Despite the first public gameplay footage videos allegedly being captured from the GameCube version of the game by video game news reporter, IGN, the planned version for Nintendo's system never saw the light of day and was cancelled early on in development.
According to rumors, the GameCube port was cancelled because the disk couldn't hold the necessary amount of data; however, a more plausible reasoning behind the cancellation was the likeliness of the poor sales of third party games on Nintendo's hardware, and the combined poor sales and reception of the PlayStation 2 and Xbox 360 versions of the game altogether.
