List of Sonic Team games
In addition to the "Sonic" series, the company has developed other games for Sega, such as "Nights into Dreams" (1996) and "Billy Hatcher and the Giant Egg" (2003). The 1991 release of "Sonic the Hedgehog" is considered significant in video game history, as it increased the Sega Genesis's sales and Sega displaced Nintendo as the leading video game company. Some of Sonic Team's games, such as the Genesis-era "Sonic" games and "Nights", are considered by critics to be among the greatest video games ever released.
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).
