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's Ultimate Genesis Collection
Sonic's Ultimate Genesis Collection (Sega Mega Drive Ultimate Collection in PAL regions) is a compilation of video games developed by Backbone Entertainment and published by Sega for PlayStation 3 and Xbox 360. The compilation features 48 Sega games (49 counting two versions of "Altered Beast") which were previously released for the Sega Genesis (including most of the "Sonic the Hedgehog" titles released for the system), arcades and the Master System. It is the sequel to the "Sega Genesis Collection" released previously for the PlayStation 2 and PlayStation Portable, however it is similar to that compilation because it contains 16 (in NTSC regions) more games (including unlockable extras).
