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 Spinball
The game was developed by the American staff of Sega Technical Institute, as the Japanese staff was occupied with developing "Sonic the Hedgehog 3" and "Sonic & Knuckles". When Sega management realized that "Sonic 3" would not be completed in time for the 1993 holiday shopping season, they commissioned another "Sonic" game that would be. The game was hastily designed amid time constraints, with most work taking place over two months. "Sonic Spinball" was released for the Sega Genesis in November 1993, and for the Game Gear and Master System in 1994 and 1995, respectively.
