Unreleased Super Mario game
Super Mario’s Wacky Worlds was an unreleased Mario world sequel for the Phillip’s CDI console. It would have involved Mario exploring levels based on historic places, such as Egypt and the Trojan horse, along with unique themed levels such as jungles, haunted houses, etc. it was eventually scrapped, due to the commercial failure of the Phillip’s CDI console. The image above is one of the only three known prototype discs left. This is sad, because this definitely could have been one of the greatest games on the CDI, and would’ve been a great addition to the Mario series.
