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" to allow for new modes and/or playable characters in 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).
