The Sonic Adventure duology is an often celebrated, yet somewhat bizarre part of the Blue Blur’s history. While a lot of people tend to say that Sonic had a “rough transition to 3D”, this is only somewhat true. It technically happened one console generation after Super Mario, but with Sonic Adventure, Sega’s flagship series was successfully integrated into the new 3D culture. Sonic Adventure and its sequel are fondly remembered for introducing the characters’ modern designs and personalities, as well as some new characters that stuck around like Shadow the Hedgehog. They are also loved for semi-serious plotlines, Chao Garden modes, and fun soundtracks.
