Sonic CD Intro [HD]

This 1993 main platform game sends you to the Little Planet to stop Dr. Eggman from controlling time using the Time Stones. The core loop involves high-speed traversal across levels, uniquely featuring time travel mechanics where reaching high speeds allows you to jump between Past, Present, and Future timelines. To achieve the best ending, players must strategically alter the past by destroying Eggman's machinery in earlier eras. This title has received at least one remaster since its original Sega CD release.
