OBS:I've played the Xbox 360 version.I'm just submitting this review to the PS3 version because it seems that it's more viewed.Also,sorry for my English.
Okay,let's start.This is my first review,so,sorry if it isn't good.Sonic the Hedgehog or Sonic 06 is a very underrated game.the game isn't perfect,of course,it's unfinished,but it isn't as bad as people says it is.I'll explain this:

Graphics:This is the first Sonic game for 256 bit consoles,so,it try to be realistic.The scenarios are pretty good,so are the main characters models,but some animations are weird...if you played the game you know what I mean.The town stages felt strange by the graphics in some way too,but I don't know exactly why,it just seems like a beta.It could be more...smooth...I'd just say that it look like it needed some more visual effects.By the way,the graphics are still good in overall,especially for the level scenarios and the CG cut scenes are perfect.I originally gave it a 7,but now i'm sure it deserves an 8.

Sound: Surely,it's the Sonic game with the best theme songs:All Hail Shadow,Dreams of an Absolution and,of course,His World.the other in-game musics are also good and fit in the stages,and there is at least 3 musics per stage!This will get a 10.

Addictiveness:Like the Sonic Adventure series games,this game have lots of optional missions .I mean,to complete the game 100% you must beat all levels with a S rank,including in the hard mode,collect all silver medals  hidden in the stages and beat all the town missions with S rank.By the way,unlike the Adventure series games,where you got a reward for completing everything in the game,here you get nothing with the exception of the town missions,where you get some extra rings.Those rings can be used to buy some items in a shop,but few items are available for Shadow and Silver.I mean,you can still enjoy it,but what's the point of doing everything if you get nothing?I've enjoyed replaying the missions because,as I said,I have the Xbox 360 version,and in that version you can unlock various achievements by progressing through the game,but the PS3 version has no trophies,so,it will get a 5.

Story:I like the game's story because it's darkest and emotional.I'm not talking about Sonic and Elise "love story",because I think that was a big error in the game story,but besides that,the story is still good.I haven't seen any "plot holes",just that,if Blaze is from the Sol dimension,why was she in Silver's ruined future?And if Shadow was pursued by GUN many times,why is he a GUN agent in this game?I think we can call it ''mysteries'' other than errors.The story will get an 8.

Depth:I'll rate this with pros and cons:
Pros:
-4 playable episodes
-9 playable characters
-Huge hub worlds
-Lots of optional missions
-Each character have different game play mechanics,but not with drastic changes.
-Sonic can unleash his full speed in the speed sections.
-The characters have many abilities.
cons:
-Very long  loading screens.If you have the Xbox 360 version,you can download the game at your hard drive to help,but we're talking about the PS3 version,so...
-The many glitches in the game.luckily,only about 5-10% of them will disturb you during the game play,mainly in Sonic's speed sections,but they still exist.
-Some times you can see by yourself how the game is unfinished...
Here's a basic explanation about how the character's game play works:

--Sonic:Mostly like in Sonic Adventure 1 and 2.Sonic race through the stages while quickly defeating enemies and trying to reach the goal as fast as possible.There are high speed sections where you cant stop running and must avoid the obstacles.
-Tails:Can fly and throw item boxes at enemies,therefore his flight is hard to control
-Knuckles:His game play is mostly based in exploration and battle.He can glide and climb walls,therefore,he can easily get stuck while climbing.
--Shadow:His levels are longest than Sonic's.He can use vehicles and have more battle moves
-Rouge:Mostly like Knuckles,she can glide,climb and get stuck o walls.The only difference is that she throws bombs at enemies instead of infighting.
-Omega:I don't have much to say about him...just that he shots at enemies and can glide.repedeadly pressing the X button will make it glide much further.
--Silver:He can use his psychonesis to throw objects at enemies,or stun and throw enemies at other enemies.He can also use his psychonesis in himself so he can float.Like Omega,repeatedly pressing the X button will make him go further.
-Blazehe has an attack similar to a homing attack,so,her game play is similar to Sonic's, and can double jump.
-Amyhe can also double jump and become invisible.the only way to attack enemies while playing as her,is with her hammer.

By the way,the game play is still great and you will have fun while playing it,but due to it's flaws,I'll only give it a 7.

Difficulty:Like Sonic Adventure 1 and 2,the game itself isn't so hard to beat,but it's nearly impossible to complete 100% of the game.I mean,how many people can complete every mission and stage with a S rank?That's all I have to say about the game's difficulty.I'll give it a 7.

Overall:7,6onic the Hedgehog has it's many flaws,but it isn't as bad as people says,a good rating for this game is between 6,5 an 8,0.If you don't like it,try playing by yourself,not only the first levels,but an entire episode and you will probably change your mind.If you like it,you can help by writing a review about it in sites like Metacritic.I don't want to make everyone like the game,just that they have in mind that it isn't that bad.And that's it!Thanks for reading and please,rate my review.

I had always heard about how this was the worst Sonic game they ever made, but even having not played anything newer than Sonic Advance 2 or Shadow the Hedgehog, I always had my doubts about it being the worst. A lot of people don't know anything about Sonic Labyrinth. After reading your review, I've decided that I may actually give this title a try when I get the chance, even though I never really liked the Sonic Adventure games. It'[s not the most in-depth review of a game I've ever read, but it's not bad for a first. Also, if you don't mind me asking, what's your first language?

m0ssb3rg935 : My native language is Brazilian portuguese.It's surprising how I had a reply 1 hour after writing the review!Thank you for reading.And,yea,the review could've been better.It's mostly because I was in a hurry.But i've updated the review.

tornadocam : I actually like the game.It has many flaws,but as I explained in this review,it's actually a good game and I had lots of fun playing it.

ultrasonic2 : Very good review here. But I am going to be blunt and say my opinion of it and what my feelings are. There are somethings I like about the game. The rest I hate. Why? Mainly because of the storyline. That's where the hate is. I don't need to go into details as of why. But the gameplay and the soundtracks for me are amazing. Especially sonics theme song. I like it more of instrumental than the singer singing it. I hope this doesn't offend you. Its mostly the storyline of this game I despise and you can see why. And you can see why others very much hate it too. Heck, it wasn't even fair to poor Amy. Who some people don't like. I like Amy she may sound annoying, but she has her reasons of being that way. 

Eniitan : There's no way your opinion offends me!I see you have your reasons to dislike the story.Thanks for the reply.
