Sonic Gems Collection

From the original Sonic the Hedgehog to Sonic Frontiers and beyond, we focus on where it all began: the video games. We also cover the many game prototypes that have to come to light over the years. But we don't stop there. All things Sonic have a place within, including comics, TV shows, books, music... and Chao In Space.
