Crazy Credits

There are several Chaos Emeralds hidden in bonus levels throughout the game. If you collect them all, after the credits roll at the end of the game, Dr. Robotnik will be seen jumping up and down over the words THE END. However if you do not collect all the emeralds, following the credits will be Dr. Robotnik juggling the ones you did not collect and standing over the words TRY AGAIN. See more »

The Odyssey Begins!
26 June 2003 | by (Buffalo, NY) – See all my reviews

Here it is, the very first game of Sonic the Hedgehog ever released. This is the very game that started the continuing adventures of a blue hedgehog, up against a mad robot scientist.

The story here is basically the set-up for all subsequent games of the series. Sonic is on the planet Mobius, trying to stop Dr. Robotnik (a.k.a. The Eggman) from taking over the planet. Sonic has to travel in different environments, collecting as many rings as possible, and restoring his forest friends from the robot badniks they were transformed into.

First, there's Green Hill Zone (the tropical region), then Marble Zone (the mountains), Spring Yard Zone (a pinball garden of sorts), Labyrinth Zone (an underwater maze), Starlight Zone (the big city at nite), Scrap Brain Zone (industrial park), and the Final Zone (Robotnik's lair). The first six zones each have three acts, topped off with a different boss (the segments where Robotnik tries to stop Sonic from catching up with him). The last zone ultimately defeats Robotnik (at least in this chapter).

In between, you have to try collecting six chaos emeralds in a special stage. This prevents Robotnik from using them to his own advantage(s).

So, here it is; the game that started it all. Sonic would later be joined by several other characters (known as "freedom fighters") as they would all travel to more adventurous settings, and be up against progressively dangerous schemes from Dr. Robotnik.

Next up: Sonic 2!
