SEGA announced last year that they are working on a special HD collection of the classic SEGA Mega Drive games Sonic the Hedgehog, Sonic the Hedgehog 2, Sonic CD, Sonic & Knuckles, and Sonic 3. The collection is titled the Sonic Origins collection and is being created as part of the Sonic’s 30th anniversary which happened last year. We haven’t heard much since the original announcement, so it’s great to hear that the collection has been rated in South Korea. Hopefully this means that SEGA will share more information on Sonic Origins soon.
