CERO: n/a (not rated)
ESRB: EC (Early Childhood)
Sonic the Hedgehog's Gameworld ( is a game developed by ソニック・ザ・ヘッジホッグゲームワールド ) ? Aspect Co. Ltd for the Sega Pico. It is a party game featuring Sonic the Hedgehog, Miles Tails Prower, Amy Rose, and Dr. Robotnik/Dr. Eggman, and features many different mini-games. It was released in Japan in August 1994. It was not released in North America until two years later in November 1996, and it was never released in Europe.
Differences between Japanese and North American versions
Compared to the Japanese version, games featuring gambling, fortune-telling, fantasy violence, rock-paper-scissors, and other noneducational elements were omitted from the North American version. This means that the entire third page from the Japanese version is eliminated and the remaining games are in different locations than in the Japanese version.
Roulette mini-game removed for the American version
The North American version replaces the pilfered non-educational content with a drawing page for young players to create their own designs. 
The music that plays on the first three floors is a remix of the title music from . Sonic the Hedgehog 3
