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 Mega Collection
"Sonic Mega Collection" features twelve to fourteen complete games in one retail unit. All games are ports of their original versions on the Sega Genesis. High-resolution instruction manual scans are included for each game. Also included is an "Extras" section featuring over 100 scans of "Sonic the Hedgehog" comic covers, illustrations of "Sonic" characters throughout the franchise's history, and a handful of videos promoting other "Sonic" games, including the beginning and end sequences to "Sonic CD". In addition to the seven default games, three unlockable games are included that recreated the "Sonic & Knuckles" "lock-on technology" by allowing players access to new gameplay features and special stages by opening the hatch of the "Sonic & Knuckles" Sega Genesis cartridge and inserting another compatible cartridge, in this case each of the first three games in the "Sonic the Hedgehog" series. Also, four games published by Sega but not in the "Sonic" series could also be unlocked (two in the North American version).
