Sonic Origins marks the first time since 2011 that Sonic the Hedgehog 3 & Knuckles has been re-released.
The release date for Sonic Origins, 23 June, is the same date as the release date for the original Sonic the Hedgehog in North America. It is also considered the canonical date of birth for Sonic. It was also the release of the Plus expansion the year afterwards.
Sonic Origins marks the first time the 2013 ports of Sonic the Hedgehog and Sonic the Hedgehog 2 will be fully available for PC and consoles.
The 2.0.1 update made Tails in Sonic 1 unplayable due to the game crashing when entering the waters of Labyrinth Zone. The only way to avoid the crash was to bypass the level by using debug mode. This issue was fixed in the 2.0.2 update.
Due to rights issues regarding the music used in the Carnival Night Zone, Ice Cap Zone, and Launch Base Zone, replacement music was used instead.
