List of Sonic the Hedgehog video games
"Sonic the Hedgehog" is a video game series. It is published by Sega, with entries developed by Sega, Sonic Team, Dimps, SIMS Co., Ltd., BioWare, and Sumo Digital. The series debuted in 1991 with the video game, "Sonic the Hedgehog", released for the Mega Drive video game console (named Genesis in North America). Most "Sonic the Hedgehog" games have either been platform games or released for Sega video game consoles and handheld game consoles (handhelds) dating from the Genesis to the eighth generation of video game consoles (2012–present). However, some of the original games were ported into versions on third-party home consoles and developed by several companies. As of February 2013, the series has collectively sold over 85 million copies worldwide across both the platform games and spin-offs.
Home video game console
To compete with emerging next gen consoles, Nintendo released Donkey Kong Country which could display a wide range of tones (something common in fifth-generation games) by limiting the number of hues onscreen, and Star Fox which used an extra chip inside of the cartridge to display polygon graphics. Sega followed suit, releasing Vectorman and Virtua Racing (the latter of which used the Sega Virtua Processor). Sega also released the 32X, an add-on for the Genesis, while their Sega Saturn was still in development, and announced that they would replace the Genesis with the Neptune, a combination 32X and Genesis, and sell it as a budget console alongside their upcoming Saturn. Despite public statements from Sega claiming that they would continue to support the Genesis/32X throughout the next generation, Sega Enterprises quietly killed the Neptune project and forced Sega of America to abandon the 32X. The 32X's brief and confusing existence damaged public perception of the coming Saturn and Sega as a whole.
