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.
Sonic Gems Collection
"Sonic Gems Collection" is a compilation of obscure video games published by Sega for various consoles, such as the Sega CD, Sega Saturn, and Game Gear. It primarily focuses on "Sonic the Hedgehog" games, such as "Sonic CD" (1993) and "Sonic the Fighters" (1996). It also includes six of the twelve "Sonic" games released for the Game Gear. These games encompass various genres, such as platforming, fighting, pinball, and puzzle. Additionally, players can unlock several Sega Genesis games unrelated to "Sonic", including the two "Vectorman" games (1995 and 1996). Four games in the international version, "Bonanza Bros." (1990) and the "Streets of Rage" trilogy (1991—1994), are not included in the North American version. Each game is mostly identical to its initial release, but some were changed; for example, "Sonic R" runs at a higher frame rate.
