Time travel is the idea that sets Sonic CD apart. Released in 1993 and directed by Sonic's designer Naoto Ohshima, it takes place on Little Planet, a world that appears over a lake once a year and that Dr. Robotnik has taken over. Running past a Past or Future sign and then keeping up top speed for a few seconds sends Sonic to a different version of the same zone. In the past, he can find and destroy Robotnik's machine to create a Good Future, and doing so in every zone changes the ending.
The game also introduced Amy Rose and Metal Sonic, whose race through Stardust Speedway is one of the series' best-known moments. Special stages are pseudo-3D arenas where Sonic chases UFOs to collect Time Stones. The North American release replaced the Japanese and European soundtrack with a new score by Spencer Nilsen and others, and fans still argue over which version is better.
Tips for Sonic CD
After passing a Past sign, find a long flat or downhill section to keep up speed until the time warp triggers.
In the past, look for the robot generator and destroy it; it is the key to the Good Future in each zone.
Collect all Time Stones in the special stages as an alternative route to the best ending.
