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
Morawiec believed that the game would face "acceptance challenges" from both fans and the gaming media, as "Sonic the Hedgehog Pinball" strayed away from the traditional platforming genre. After returning home to the United States from Europe, Morawiec was surprised to find that the game had sold well, and was pleased that it benefited from the franchise's popularity. Nonetheless, he regretted that the team had lacked time to "polish" the game properly. After the Game Gear title "Sonic Drift" received poor reviews in Japan, Sega released an 8-bit port of "Sonic Spinball" for the Game Gear in its place worldwide in late 1994. It was also released for the Master System in Brazil and Europe in 1995. The 8-bit version is mostly identical to the Genesis game, albeit with downgraded visuals and different, more platforming-oriented bonus stages. The Master System version was released near the end of the console's lifetime and did not sell well, and became a valuable collector's item.
