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 Mega Collection
"Mega Collection" was developed by Sonic Team, the studio behind most games in the "Sonic" series. According to director Yojiro Ogawa, Sonic Team's goal with the compilation was to introduce children to older games in the series and showcase what made "Sonic" successful. Sonic Team chose to focus on including all the Genesis "Sonic" games. Rather than porting them from the Genesis, they collaborated with VR-1 Japan to develop an emulator to run the games' ROM images. Series co-creator Yuji Naka, who served as producer, said the team intended to include the 1993 Sega CD game "Sonic CD", but storage constraints prevented this. Sonic Team also considered including BlueSky Software's "Vectorman" (1995), and "Sonic R" (1997) and "Sonic Shuffle" (2000) were expected to appear in "Mega Collection" at one point. "CD", "Vectorman", and "R" later appeared in "Sonic Gems Collection" (2005), a successor to "Mega Collection" focusing on rare "Sonic" games. Sonic Team had trouble gathering materials for the compilation because it had been a decade since they made the games and "Sega's not that good about keeping history." For instance, Naka wanted to include the original prototype of the first game but Sonic Team could not find its ROM image.
