Thirty years of the saga are read here decade by decade, from Mega Drive cartridges to the open world. The 1990s set Sonic up as Mario's direct rival and stack up the milestones: Tails in 1992, Amy Rose and Metal Sonic in Sonic CD, Knuckles in 1994, the Lock-On cartridge of Sonic & Knuckles, then the successful move to 3D with Sonic Adventure on Dreamcast. Next comes the decade of experimentation, between Shadow's arrival in 2001, the Werehog concept and the shipwreck that was Sonic 2006. Then follow Sonic Mania, made by fans turned developers, and the free-roaming gameplay of Sonic Frontiers.
From the Mega Drive to today's consoles, Sonic the Hedgehog has sped through more than thirty years of video games. Rather than an exhaustive catalog, here is a timeline of the major milestones that have shaped the saga, decade by decade.
