Despite both Sonic Adventure games being well-received in their own right, when compared to the classic games of the Genesis Era, a lot of players feel as though they don't match up. The Dreamcast Era of the Sonic series marked the first step into 3D, and what many consider to be the point where the games first dipped in quality. Sonic Generations looks to show us how the series has evolved with time, and the latest trailer for the game clearly shows this evolution. Still, the core aspect of high-speed platforming has remained consistent, which is why the series has survived to this day - despite some people giving up on it. The Sonic the Hedgehog franchise has made some changes with time, though not always for the better.
