Introducing Amy Rose, Metal Sonic, and the Time Stones this is the first and only Sonic game to come out for Sega CD, with new characters, 3 endings, and anime entrances and closings this is considered by Sonic fans as one of the best Sonic games of all time! It came out in November of 1993, along with Sonic Spinball and was just rereleased for the PC in 1995, and the features are the same, the codes, the characters, everything. The only difference is that this time around they got Amy Rose's name right in the instruction booklet. This game presents time travel; Sonic can go into the past, present, and future realities of each zone! The future depends on whether you trash Robotnik's roboticizer in the past of each act; if you do, the future will be a good future where the animals are allowed to run free. If not, it will be a bad future where Robotnik is allowed to run amok. If you get the Roboticizers in the past of every act, you will see the good ending of the game. Otherwise, you'll see the bad ending...This game consists of the Palmtree Panic Zone, Collision Chaos Zone, Tidal Tempest Zone, Quartz Quadrant Zone, Wacky Workbench Zone, Stardust Speedway Zone - possibly the most famous Sonic Zone and the race with Metal Sonic - and the final confrontation with Robotnik, The Metallic Madness Zone!
Dr. Robotnik's latest scheme involves the mysterious Little Planet, which appears on the last month of every year over Never Lake. The Little Planet houses the seven Time Stones, with which the holder obtains the ability to travel through time and space. With the control of time, nothing could stop the Eggman! Not to freak, because Sonic the Hedgehog is on the case! Unfortunately, Robotnik has decided to unleash Metal Sonic to keep the hedgehog hero at bay; and kidnap Amy Rose to further complicate the problem. Infact, Robotnik's already made use of the Little Planet's lack of any boundaries on time, and has placed robot machines in the past so he controls the future. Now Sonic's got to stop Robotnik, destroy the robot machines, collect the seven Time Stones, save Amy Rose, and deal with Metal Sonic on a tiny planet where time has no meaning. A hedgehog's work is never done....
