Description official descriptions

Yet again Sonic and friends find themselves wrapped up in the schemes of Dr. Robotnik. This time he plans to exploit the power of Chaos, a malevolent being that feeds upon the power of the Chaos Emeralds. In their own way, five heroes will do what they can to save Station Square and, perhaps, the entire world.

The player can select from which character to play after meeting them with Sonic, and each has its own unique version of each level. Sonic's levels involve racing through a level as quickly as possible, destroying any robots along the way. Tails can hover over distances, and his levels are similar to Sonic's except that he must beat an opponent to the finish line. Amy can't charge up ramps or run as quickly as Sonic and Tails, but she does have a giant hammer she can break obstacles with. The goal of her levels is to avoid being captured by a robot sent after her by Dr. Robotnik. E102 Gamma is a slow, difficult to maneuver robot, but it has guns and missiles that can lock on to several targets at once, chaining together attacks and earning a higher score and more time on the clock. The goal of its levels is to reach a boss enemy and destroy it before time runs out. The final character is Big the Cat, a fisherman searching for his lost frog. Big's levels are almost entirely devoid of action or fighting; he just fishes. Each character can find items that increase their abilities as the story progresses, such as a ring for Sonic that lets him home along lines of rings, or improved lures for Big. A final chapter wrapping up the story is unlocked after all other characters have been completed.

Additionally, each of the characters can visit the Chao garden where they can raise baby Chaos. By petting, feeding, and showing animals found in levels to the Chaos they can grow stronger, and optionally be put into races against other Chaos. As well each level in the game has additional objectives that can be completed to acquire extra emblems, although the emblems don't do anything in this version of the game. Finally, at one time it was possible to go online and download additional levels and bonuses in the game, such as a Christmas theme for Station Square and a level sponsored by AT&T, but since SegaNet shut down this is no longer possible.

The best Sonic game since S&K.

The Good
Most of the Sonic levels are great, have a lot of running about, but also plenty of platform-jumping as well. There are original ideas, such as the stone snake and the mirrors in Lost World. The graphics are amazing, and there are some first-rate pieces of music. The Sonic levels have great replay value.

The Bad
The Knuckles levels become tedious (wandering about looking for pieces of an emerald, helped only by a less-than-useful tracking device). And as for the 'Big the Cat' levels. A fishing simulator? What on Earth were the makers of this game thinking of? Big himself is a pretty uninteresting character. The voices in this game are worse than abominable - Sonic and friends sound like spoilt brats - and the jokes are unfunny. Cut-scenes which could have been atmospheric are ruined by the terrible voice-overs. This game somehow fails to be greater than the sum of its parts.

The Bottom Line
Sonic and friends are once more called into action when the nutritionally challenged Dr Robotnik brings into being a liquid monster which he plans to use in his latest attempt to rule the world. This is a fully 3-D, multi-role platform adventure in which you must guide Sonic, Tails, Knuckles, etc through the various levels completing whatever tasks they are required to complete. Robotnik and his creation will turn up now and again, providing boss sequences, and there are times when you will need to explore the landscape in order to find entrances to further levels. All in all, the best Sonic game since Sonic 3/Sonic and Knuckles, but I still think those Genesis 2-D scrollers were the best Sonic games.

The First Adventure ... Begins

The Good
The game is in fact okay for the Dreamcast but the GameCube version is much better! Who needs a Dreamcast these days? I found it a little good at the beginning of Sonic's story but I couldn't do it very well... But after one week or so I found so easy!

The Bad
It's got an interesting storyline. But the graphics are rubbish! Like, I said the GameCube version is a LOT better!

The Bottom Line
The storyline is cool. But the only good story is Sonic well that's my words. I discovered Tails, Knuckles, and Amy's adventures so easy. Gamma's story is okay but not as good. Big's story is really rock solid!.

The long storyline goes on in Sonic Adventure 2, then throughout Sonic Heroes.

Without a doubt, the best game I ever played!

The Good
Since the very first Sonic the Hedgehog in 1991 I was completely hooked on the character. This game brings a whole new dimension to him. What I like about the game is it is more fast paced that the previous, the environments are incredible, they keep all of the robots from previous games and the final boss was actually a challenge to defeat, which, nowadays, is quite rare in final bosses. The characters of the 3D game are successfully taken from the original 2D environment, the new characters, including Big, are I think a huge success and, most importantly, they remain true to the spirit of the game.

The Bad
What's bad about this can't think of anything, even though many critics probably have some things to pick at.

The Bottom Line
If I still had my Dreamcast, Sonic Adventure would be the most used game on it. This game is an absolute must-have if you're a fans and a must-try if you're not.
