(Overall) Sonic the Hedgehog Chaos was released in 1993 for the Sega Master System and Sega Game Gear. This game has been rereleased several times over the years on consoles like the Nintendo Gamecube, Playstation, and Xbox. In Sonic Chaos you have they choice to play as Sonic or Tails. Sonic is faster than Tails and can use the spin dash attack and can do the super peel-out which first appeared in the game Sonic CD for the Mega/Sega CD. Tails is slower than Sonic but can fly by pressing up and hitting hitting button 1. This is one of the few games that when playing as Tails you can fly. The other difference between playing as Sonic and Tails is that when playing as Sonic you must collect Chaos emeralds to win the game. Tails cant get the Chaos emeralds so it makes the game much easier when playing as Tails. To get the Chaos emeralds when playing as Sonic you must collect 100 rings to get to the special stages. Each special stage is different unlike in most of the Sonic the Hedgehog games. When you run out of time or get the Chaos emerald in the special stage you are sent to the next act.
(Graphics) Remember that this game is for the 8 bit Sega Master System not the 16 bit Sega Genesis! For 8 bit the graphics are stunning. The Sega Master System was know for having impressive graphics and Sonic Chaos is no exception. The backgrounds are colorful and nice to look at. Take the graphics of Super Mario 3 on the Nintendo Entertainment System and Sonic Chaos and compare them and you will see how incredible the graphics really are.
(Sound) The music is one of my favorite things about this game! It is crisp and funky fresh sounding. This is one of those games you turn the volume up to max on your TV or computer. It doest sound as good as its 16 bit Genesis counter parts but like I have said it is on an 8 bit console. The sound effects are also really good. Sonic Chaos has a nice variety of music that is fun and catchy.
(Addictiveness) This game is very short. If it was longer or took or time to beat I would have gave it a 10. This is a very fun game and one of the best Master System games I own and have played so I play it just about every time I play a few Master System games. Depending on how much you like this game you may play it every day or just once. Addictiveness is in the eye of the beholder.
(Story) As in most Sonic games the story is about the same, Dr. Robotnik is up to something and you have to stop him. Unless you own the game and have the instruction manual you really wont know the story. Robotnik's at it again! For a year after the six Chaos emeralds were restored to South Island, all was peaceful and quiet... Except the occasional sonic boom as Sonic the Hedgehog and his friends Tails practiced their speed runs. Then one day, the island was rocked by a terrible explosion. Great chasms opened up in the ground. Strange new landmarks sprang into being. The animals, including Sonic and Tails immediantly began searching for the cause. It was Flicky the Bluebird who answer "the Chaos emeralds are missing from the North Cave!" Tails frowned. "If the sic emeralds are separated, there's no balance, and chaos'll leak out all over the world! And if we don't find them fast, South Island will sink into the ocean!" At that moment, a strange round flying machine roared overhead. Clutched in large pincers on its underbelly was the red Chaos emerald! All the animals could see of the pilot was his bushy mustache and big red nose, but his nasty laugh was unmistakable- Dr. Robonik! "This time nothing can stop me! Once I have the other five Chaos emeralds in my possession, I will rule the world! HAA, ha, ha, ha, haaaaa!" Then the evil Dr. Robotnik and his flying machine vanished over the horizon. "Not if we find 'e, first," said Sonic. "C'mon, Tails. Let's get those emeralds!" That is the story you will get if you read the instruction manual.
(Depth) This game has six levels with three acts in each level. If you play as Sonic you will also have to complete the special stages. Really it should only take you may be a half hour to an hour at most to beat this game.
(Difficulty) This game is pretty easy overall. The only part of Sonic Chaos you will have any trouble beating is the final boss, but even that isn't to hard. If you play as Tails this game is a total breeze. All the bosses have very predictable patterns.
