About Cabbage

Cabbage was a canceled breeding simulator video game that was planned for release in the late 1990s on the 64DD, an expansion peripheral for the Nintendo 64 console. The prototype was developed by a team of Nintendo's "biggest talents", led by Shigesato Itoi, Tsunekazu Ishihara, Shigeru Miyamoto, and eventually Satoru Iwata. Miyamoto spoke eagerly about the innovative development of Cabbage across the years until early 2000. Years later, he reflected that it had drifted silently into cancellation but that it deeply influenced other Nintendo games such as Animal Crossing and Nintendogs.
