The team now in charge of Sonic says it is determined to rectify past mistakes.
Sonic games have suffered from inconsistent quality recently, particularly with 2014's Boom.
Sega is really - as of this last year - putting a huge emphasis on quality,” said Chief brand officer Ivo Gerscovich.
One of the things about Sonic Boom: Fire & Ice is that we held the title for a year, which is not something Sega has traditionally done, but this focus on quality is really about trying to take Sonic back to where it used to be.”
