Fantastic Dizzy (The Fantastic Adventures of Dizzy outside Europe & Australia) is a 1991 video game developed by Codemasters. It was published to several platforms, including Sega Mega Drive/Genesis, Master System, Game Gear, NES, Amiga and DOS.
The game was originally intended to be released in time for Christmas in 1990, but because of a legal action between Codemasters and Nintendo over the Game Genie the title was released in April, 1991 missing the Christmas rush it was originally slated for, and only sold 125,000 units instead of the expected 500,000. Despite this, the game was awarded the NES Adventure Game of the Year 1991 by Game Players Magazine and given the coveted Parents Choice Award.
