Ending (not by me)
-Leave Sonic still for 9 minutes in Sonic CD. He'll say a special message to you, commit suicide, and you'll get a game over screen.
-Scrap Brain Zone was originally called Clock(W)ork Zone. The W sprite was never made.
-The background music for Star Light Zone is loosely based on "Kusuriyubi no Kesshin" by the famous J-Pop band Dreams come true. DCT did the music for sonic 1 and sonic 2.
-Labyrinth Zone original had a different background. It was more brown, and looked like a cave.
-Spring Yard Zone was originally going to be called "Sparkling Zone"
-Marble Zone originally had flying UFOs in the clouds. The art can still be found in-game.
-It took the dev team a full half year to create the iconic Green Hill Zone. It was completely scrapped and redone several times. The dev team knew they had to absolutely nail the visuals and level design as this would be the level that would hook the world on Sonic the Hedgehog.

The plot to sonic CD is awesome. Every so many hundred of years, a small planet orbitting earth appears in this desert. The planet, aptly named "the little planet" is said to be the home of mysterious time gems known as the time stones. People who possess these stones are said to be able to manipulate time itself. Sonic, being the cocky asshole he is, decides to go to the little planet to see if he can outrun time itself. However, when he gets to the place where it should be, he sees that Dr. Robotnik has chained the little planet to earth, and is using the time stones to conquer the little planet, and then earth.
Sonic CD is awesome for many reasons. One of the reasons I like it so much is that, unlike other sonic games, you can actually see what happens if you "lose." I.E. if you don't stop robotnik, you can see what will happen. Each level begins like normal, but there are additional lamp posts labelled past and future. After collecting these lamp posts, you can time travel by maintaining a maximum speed for a set ammount of time. After you do so, you'll either travel forward or backwards in time, and the entire level (art, level structure, bad guys, traps, etc) change too. It's fucking ace.
Dr. Robotnik has traveled into the past and set up Egg Robo's (the things that turn animals and, in the case of Sonic CD, plants into robots) to speed up his process of taking over the planet. In addition, metal sonic is in each stage, scaring off the animals. If you don't travel to the past and destroy these egg robos, then the future is dark. Essentially, you've lost and Robotnik has won. Travel to the future in any normal sonic zone without freeing the past, and it'll be very dark.
I'll illustrate the differences:
This is all the same level, same location. Stardust speedway. Top left is the past. Top Right is the present. Bottom Left is the bad future. Bottom right is the good future.
So you have to travel to the past in each level, find the egg robo, destroy it, and destroy the metal sonic hollogram, in order to make the future good. I.E. "Sonic made a good future in Zone 1."
Act 3 always takes place in the future. Which future it takes place in depends on what you do in acts 1 and 2. Make good futures in acts 1 and 2, and act 3 will be a good future. Miss either act, and it's bad future.
Oh, and another neat tidbit about Sonic CD that's not immediately noticeable - Badniks age in Sonic CD. It's a pretty neat idea that really helps keep the whole "Robotnik is evil" theme running. Badniks that appear in the past will appear in the present in their normal locations. Except they'll be severely aged, as though Robotnik hasn't kept them in top shape. In the (bad) future, they're totally gone, and all remaining badniks (i.e. those from the present) appear aged.
Aged badniks look different, and sometimes act different. For example, this is Kumo-Kumo from the present:
and this is the aged Kumo-Kumo:
The aged one doesn't jump as high and can't shoot web. Another rather depressing tidbit about aged badniks is that they all seem rather depressed. Their eyes are usually drawn in a saddened state:
Really kinda sad when you notice it.
Sonic CD contains the first appearance of Amy Rose (incorrectly named Sally in the US manual). It's also the only Sonic game produced by Naoto Oshima, the person who created Sonic the Hedgehog. And it's bar none my favorite game of the series. In my opinion, everything in the game is done to perfection. The art style, the level layout, the music, the intro and ending, everything. Sonic CD is Sonic perfection in my humble opinion.
