Sonic Adventure (Japanese: ソニックアドベンチャー) is the first Sonic the Hedgehog platformer released on the Sega Dreamcast, in turn being the first main title in the series done entirely in the still-new form of 3D gaming. The game marked a new era in the franchise, with a completely different feel and style than what was found in the 16-bit era. Originally referred to as Sonic RPG, the intent was to give a Sonic game a more adventure feel, with a greater emphasis on characters and story than was found in the classic Mega Drive titles.
