Sega had ambitious plans for the Mario & Sonic Olympic series, and wanted to bring in some big video game (and anime) icons.

Sonic the Hedgehog firmly ventured into the open-world genre with Sonic Frontiers. The franchise should abandon it now.

With the past behind him, Mario simply continued doing his thing with great titles, such as Super Mario 64 and Mario Kart 64. Then we have Sonic who basically no-showed on the Sega Saturn.

Bowser, Mario, Sonic, and Eggman are all transported back to 1964 by a handheld video game system. The Story Mode in Mario & Sonic at the Olympic Games Tokyo 2020 is surprisingly great.
