The compilation features 48 Sega games (49 counting two versions of Altered Beast) which were previously released for the Mega Drive/Genesis (including most of the Sonic the Hedgehog titles released for the system), arcade and Sega Master System. It is similar to the Sega Genesis Collection released previously for the PlayStation 2 and PSP, however it contains 16 (in NTSC regions) more games (including unlockable extras).
