Sonic Yesteryears

Sonic Yesteryears is an open-world action-adventure platform game developed by Sonic Team and published by Sega as part of the Sonic the Hedgehog series.
As a spiritual successor to both the Sonic Storybook series and Sonic Unleashed, the game follows Sonic and Tails traveling back in time with Chaos Control to certain periods in history, based on real human history, and seeking the Eleven Ornaments of the Yesteryears to stop Eggman's new evil plot. They meet the identical ancestors of their friends, help the Mobian civilians, and defend them from Eggman's ancestors.
