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 the Hedgehog 2
A version of the game for the Sega Master System and Game Gear was developed by Aspect. Though based on the original game of the same name, it is a distinct game, with different level designs and a different plot, and this version, unlike the 16-bit release, does not have the spin dash, which led it to being thought to be made before the Sega Genesis version.
