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 Gems Collection
Developer Sonic Team conceived the compilation to introduce younger players to older "Sonic" games. One game they wished to include, "SegaSonic the Hedgehog", was excluded due to emulation difficulties. Sega released "Gems Collection" for the GameCube and PlayStation 2 in August 2005. Reviews were mixed or average; critics were divided over whether the package would satisfy players. They preferred "Sonic CD" and "Vectorman", but found "Sonic the Fighters" and "Sonic R" mediocre, and disliked the Game Gear games. Some were disappointed by the absence of the "Streets of Rage" games in the American version and other "Sonic" games like "Knuckles' Chaotix" and "Sonic the Hedgehog Pocket Adventure".
