When I first played sonic CD I grew up with the 1996 PC port and I enjoyed every minute of it. Once I got the chance I went out of my way to get a Genesis emulator and SEGA CD bios and a Working Sonic CD Rom (US). Right then and there I was forever hooked. The plot is Sonic arrives at Never Lake where the fabled Little Planet (also known as Miracle Planet) is said to appear on the last month of every year. Sonic arrives to find the planet tethered to a mountain by a chain and completely mechanized. Sonic realizes this is the work of his arch-nemesis, Doctor Eggman who had set foot in this island to transform it into a giant fortress. Upon discovering Sonic's presence on the island, he dispatches Metal Sonic to kidnap young female hedgehog called Amy Rose when she follows Sonic to the mystical planet. Sonic must collect the Time Stones which are seven jewels capable of altering the passage of time itself. Having gathered all seven Time Stones throughout time, Sonic defeats Metal Sonic and faces off against Eggman. Following the Doctor's defeat, Sonic and Amy escape as Little Planet is returned to its normal and leaves Never Lake. Sonic CD introduces a new Time Travel gimmick. (In the levels there are signs marked past and future. Once you pass one and keep your speed at a constant rate you will travel back or forward through time)Sonic CD also has new Special Stages where you are in a 3D perspective and destroy UFOs for some odd reason. Destroy all the UFOs (6 in each stage) and you will obtain 1 of 7 time stones, collect all seven and all futures will be the good future therefore getting the good ending. Sonic CD has 2 soundtracks, with the JP version being the better over the US soundtrack. But I am indifferent to the 2 soundtracks, both have their hits and misses which is why sound is an 8. (CD was also the first sonic game (and video games in general) to have CD quality music.) This game was actually supposed to be the real Sonic 2 (which explains why one of the secret pictures says "SEE YOU NEXT GAME!") but Yuji Naka sent most of SEGA to the US to work on Sonic 2, while the people that remained worked on their version of Sonic 2. This also explains why Sonic CD has sprites similar to Sonic 1. Overall I think that Sonic CD deserves all its praise and I think its the Best SEGA CD game but its sales slumped (SEGA CD Sold Poorly) and because of the 1996 pc port, fans agree that this game is THE best sonic game of all time, something I wholeheartedly agree with. Just recently a port of the game made from the ground up by a man named Christian Whitehead was released for XBLA, PSN, Steam, and Mobile devices. Which also promoted Tails to playable. Both the JP and US OST are present in this port and can be changed in the menu. This port was remade with a new physics engine (the original had Collision Detection issues). So people consider the 2011 port of sonic CD the definitive version of the game. Give it a try if your curious.
