Sonic Team
Sonic Team started to work on "Sonic Adventure" in April 1997 on the Saturn with a 20-strong team. Sonic Team created the first prototype using the "Nights" engine, but the Saturn's limited capabilities made development difficult. Sega president Hayao Nakayama informed Naka of the Saturn's successor, the Dreamcast, and he believed the new console would allow Sonic Team to create the ultimate "Sonic" game. When the team learned the Dreamcast was nearing completion, they moved development to take advantage of its greater quantity of RAM, stronger CPU, and the VMU. Not wanting to waste their completed work, they placed it as a bonus in the compilation game "Sonic Jam", the final "Sonic" game for the Saturn.
