Sonic the Hedgehog 3

It's been long rumored that Sega worked on music for Sonic the Hedgehog 3 with Michael Jackson, which may be why it was removed in Sonic Origins.

Sonic Origins is a nostalgic romp through some of Sega's best platformers.

It appears Sega is pulling Sonic the Hedgehog, Sonic 2, Sonic 3, Sonic & Knuckles, and Sonic CD off of digital stores ahead of Origins' release.

According to Sonic the Hedgehog film producer Toby Ascher, the longterm plan is to make a whole cinematic universe of Sonic movies and TV series.

Idris Elba will reprise his role as Knuckles in the upcoming live-action Sonic series.
