Dizzy the Adventurer is an enhanced version of the previously released Dizzy Prince of the Yolkfolk that was bundled with the Aladdin Deck Enhancer for the Oliver twin's publisher (Codemasters/Camerica) ill-fated NES peripheral. The title had not previously been released on the Sega platforms so was originally going to be released as a stand-alone game but publisher Codemasters was uncomfortable releasing it at full price.
The game was originally released as a stand alone product as, Dizzy Panic! for the Amstrad CPC, ZX Spectrum and Commodore 64 however was included as a last minute replacement for Wonderland Dizzy. Publisher, Codemasters felt two Adventure games shouldn’t be included on the one compilation so the Oliver twins decided to leave Dizzy the Adventurer and replace (the still unreleased) Wonderland Dizzy the with Panic Dizzy to complement the other two styles of game.
Go! Dizzy Go!
Go! Dizzy Go! was originally to be released on the NES for the Aladdin however due to its unexpected failure the title was then going to be released as a stand alone title for the Sega Master System and Sega Game Gear. However the publisher, Codemasters, was uncomfortable releasing it separately at full price so was included as part of The Excellent Dizzy Collection.
