The game took approximately a year and a half to complete.
Following excellent reviews of the original, development on the sequel began very soon after at the newly established Sonic Team USA studio at SEGA's headquarters in San Francisco headed by Takashi Iizuka, a long term figure within the original Sonic Team. The original Sonic Adventure (SA) was a much welcome return for Sonic after several disappointing years prior. 'The world can be a confusing and dangerous place, especially when there are two of you! Sonic must face the new, villainous hedgehog Shadow but you must choose how the story unfolds � you can be a hero, or make friends with the dark-side! In the most thrilling Sonic Adventure ever created there are 6 playable characters, new moves to master, over 30 challenging stages and 3 different 2-player games � will you save the world or conquer it?' SA2 was such an impressive title it very much left people wondering why the Dreamcast suffered such an unfair fate.
However, since then SEGA�s, financial woes had forced the company to become a software only company and as such, SA2 the distinction of being the last Sonic game on a SEGA console ever! The creation of Sonic Adventure 2 (SA2) was a logical step for SEGA after the great success its predecessor had.
