Sonic CD is a platformer for the Mega-CD, released in Japan on 23 September 1993 and in North America and Europe on 23 November 1993. It was developed by Sega and directed by Sonic co-creator Naoto Ohshima. Its signature idea is time travel: hitting 'past' or 'future' signs sends Sonic to one of four versions of each stage, each with its own music. Future stages are 'bad' by default and turn 'good' if the player destroys a hidden transporter in the past.
Amy Rose and Metal Sonic made their debut here; both were designed by Kazuyuki Hoshino. The North American release was delayed about two months for a new soundtrack by Spencer Nilsen and David Young, so the game exists with two different scores.
With over 1.5 million copies sold, Sonic CD was the best-selling Sega CD game. In 2011 Christian Whitehead rebuilt it in his Retro Engine for Xbox 360, PS3, Android and iOS, and that version later became part of Sonic Origins.1
