- TRIVIA -


Sonic The Hedgehog : Genesis of the Genesis'! Greatest hero 'Sonic the Hedgehog' was the premier character on the home system 'Sega Mega Drive'. It is said that because the Genesis was faster than other console systems at the time (and more importantly, faster than its chief competitor, the Nintendo Super Famicom), Sonic, a hedgehog whose lone weapon is his speed, was born.


Originally, sonic's main attack was the ability to pick up things and throw them at his enemies (similar to Chip 'n Dale Rescue Rangers for the Nintendo Entertainment System), but it was scrapped because it was too complex.


The Sonic The Hedgehog character actually made his debut in 1990 as part of a promotional tour with the Japanese pop group 'Dreams Come True'. Ironically, the music for Sonic The Hedgehog (and its sequel, Sonic The Hedgehog 2) was composed by Dreams Come True's bassist Masato Nakamura.


Sonic replaced 'Alex Kidd', who was Sega's mascot prior to 1990.


The bonus stage scene was greatly inspired by Taito's "Cameltry".


Sonic The Hedgehog is a playable character in Nintendo's Super Smash Bros. Brawl for the Nintendo Wii.


MB (Milton Bradley) released a board games based on this video game (same name) : Just like the video game, the object is to collect the most rings and defeat Dr. Robotnik.
