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.
Platform game
1990 marked the release of the Super NES, along with the eagerly anticipated "Super Mario World". In order to fend off the new competition, Sega released "Sonic the Hedgehog". Whereas Nintendo's offering featured a conservative design, true to the "Mario" tradition, "Sonic" showcased a new style of design made possible by a new generation of hardware. "Sonic" featured large stages that scrolled effortlessly in all directions, as well as all manner of uneven terrain, curved hills, and a complex physics system that allowed players to rush through its levels with well-placed jumps and rolls. Lastly, there was the game's eponymous main character. Sega decided to give Sonic a rebellious personality in order to appeal to older gamers, and super speed to help show off the "Genesis"' hardware capabilities. The game proved to be a massive hit, was a successful pack-in with new systems, and cemented the view that platform games would make or break a console.
