This is the blue hedgehog's first adventure in the third dimension. Prepare yourself for strange animations, poor voice acting, and lots of glitches.

Without giving too much away, the basic story is as follows: Dr. Robotnik is up to something fishy, an ancient monster is on the loose, the Chaos Emeralds are involved somehow, and it'll take Sonic and gang to help save the day.

Sonic Adventure DX sports six playable characters: Sonic, Tails, Knuckles, Amy, E-102 Gamma, and Big. Each character has his or her own unique story, motivations, abilities, level traits, and more.

As Sonic, you will jump, dash, and roll your way through beaches, ancient temples, modern cities, and more, in a race to reach the end of the level. Along the way, you will meet new characters, learn new abilities, and will fight dozens of enemies. Sonic's levels are some of the fastest and most enjoyable ones in the game.

As Tails, you will run, spin, and fly through many of the same levels as Sonic does, but with a greater focus on flying. Many of Tails' levels are a race to the finish against Sonic, though Tails has some unique levels as well, such as airplane battles and "snowboarding" in a desert.

As Knuckles, you will search for fragments of the Master Emerald. There are three emerald pieces per level, and you must fly, dig, and punch your way through the given area to find all thee pieces. Unlike in the sequel, Sonic Adventure 2, Knuckles can search for three emeralds at once. I actually like Knuckels' levels in this game; they're a lot of fun.

As Amy, you will use your giant hammer to evade a robot that chases after you. Amy's levels are some the slowest, but offer anxiety-inducing moments thanks to jump scares and other quick "gotcha" moments. Amy's levels are some of the most boring of the bunch.

As Big, you go fishing for your frog buddy, Froggy. No joke, you go fishing. Big's levels can go on for a long time, and can be very, very frustrating. You'll either love or hate Big's levels; there is not much room in between. Personally, I enjoy them, as they offer a change of pace, and also because the permise is just so silly.

As you play, you will find new abilities and levels for each character. Some new abilities are completely optional and are well hidden, but finding them definitely helps out by making a character stronger, for example.

The music in this game is pretty good, and the sound effects are decent as well. The voice acting, however, is terrible. Like really, really bad. Though, to be fair, the game is 15+ years old, so you can't expect much in the voice acting department. Try not to take the voice acting too seriously and you'll have a good chuckle or two.

Being that this is Sonic's first 3D endeavor, it comes to no surprise that the game contains a few glitches. On several occasions, Sonic clipped out of the level during loop sections, which resulted in my death. Also, Sonic's homing attack doesn't always have a good aim, which also results in death. Just be prepared for some cheap deaths at the result of buggy collision detection.

Sonic's first 3D adventure has lots of glitches and features terrible voice acting, but it's a decent game all things considered. The levels are fun, the sound track is nice, and for being the first 3D Sonic game, it's not half bad. If you played Sonic Adventure as a child and want to re-experience some nostalgia like I did, go ahead and get this game; but if you've never played Sonic Adventure before, you may not like what you find. Glitches and all, I enjoy this game.

This game brings back so many memories. The physics of this game, especially for sonic himself, really add a nice touch and allow for some sweet shortcuts. This is probably my favorite sonic game of all time.

This game is cheesy, aged horribly, and bites off way more than it can chew, but it still has its charm underneath. The controls, regardless of the character you choose, are always smooth and responsive and the levels are big and have lots of nooks and crannies to uncover.

Public opinion on this game has worstened considerably since it's release. Some are saying it's as bad as something like Sonic 06, but that's just not giving it enough credit. Sure, I wouldn't call it "great," or even "good," but it's one of those games that really shows off what was acceptable in gaming back in the late nineties that would be laughed out of the industry today. It's like a time capsule, and one of the very few games I can recommend as "so bad it's good."

Just, for the love of God, install BetterSADX. Unless you want to fall through floors and get the camera constantly stuck on things, that is.

Sonic Adventure was originally released for Dreamcast back in 1999, and it's generally regarded as the first mainline 3D Sonic game. It really doesn't feel like classic Sonic games and was really experimental with its playstyles. The game has a hub world which you use to enter different stages, 6 playable characters and each character plays differently with a set goal:
- Sonic (beat a stage)
- Tails (race against Sonic)
- Knuckles (hunt for Master Emerald shards)
- Amy (run away from an enemy trying to kill you)
- Big the Cat (fishing)
- Gamma (3rd person shooter)

Each character's storyline is technically a small part of the main plot, and you get a better understanding once you play them all. There are also quite a lot of cutscenes. There are a few minigames such as boarding, bump car race and SHMUP.

On top of this, you have the Chao "tamagotchi simulator" where you can raise a Chao by feeding, petting and giving it animal parts to raise its statistics which are important in the Chao racetrack minigame.

I first played this game on the GameCube when it came out, and this Steam version is rather weird port on a technical level... it seems the original PC version of SADX came out in 2004, and this Steam version is actually a newer port and an inferior version. The development history looks a bit like this:
- Dreamcast (1999): Original.
- GameCube (2003): Added GameGear games, Free Camera Mode, Mission Mode and some shader effects like wobbling underwater effect. Added Chao Black Market from SA2. Removed Chao related VMU minigames in favor of GBA <-> GC connectivity.
- PC (2004): Almost the same as GC version, some obvious things were removed and also the shader effects.
- X360/PS3 (2010): Removed almost everything added in GC/PC ports, including GameGear games. DX portion was sold as a DLC.
- Steam (2011): The same as X360/PS3 version, except DX portion is included by default and isn't a DLC, but it's still missing GameGear games.

However, talented modders were able to salvage this Steam version by restoring features from the older PC version which includes GameGear games:

It also adds a few other things like able to play in higher resolutions, borderless window, playable Super Sonic as Sonic in regular stages (by collecting 50 rings) among with other features.

I only recommend to buy this version if you're planning to use Better SADX mod (which restores the game the way it should be). If not, then pass on this version. If you're looking for a better Sonic game, then buy Sonic Generations instead:

In 1998 Sonic Adventure came out, and the world was amazed. The speed, the graphics, the world. The entire game was impressive and honestly it was one of those moments where a console gets a the game that makes people want the console.

Sonic Adventure was it. I never had a dreamcast and this and crazy taxi were two games that had me jealous.

A couple years later, in 2003 the game was released on the Gamecube, and everyone got a chance to play the game, and at the time it still was a top notch game. It had some minor issues, but at the time it was still an amazing experience.

However it's not 1998, it's not even 2003. It's 2016. The game industry has greatly improved since it's release, and Sonic Adventure is outdated. There's a few obvious problems, starting with a pointless lives system. There's almost no penalty except the player has to start over. The player can farm almost infinite lives in the casino level. So why this method?

The camera is bad. In the Gamecube era gaming didn't have many examples of great cameras, but now. Well with a camera this bad, it's almost unplayable.

The levels are acceptable but there's a number of glitches. I don't remember if this was like the original version but there's a number of deaths the player will accrue because a controller isn't held in a specific direction.

In addition the best moments in the game are about the speed, but the fact is the controls don't really keep up with what the game hints that it wants to do. In fact you might be better off putting the controller down when the game really gets running at full speed. This isn't like Tomb Raider where there's a difficulty to Lara's trip down a river. Instead there's just no point to really be in control at these parts of the game. And they're the best parts of the game, sadly.

Then there's the "Story" And animation. This was one of the first 3d games and it shows. The animations and voice acting are both weak. The story is typical sonic fare, but the way it's delivered is embarrassing.

The final nail in the coffin of the game though is the flow through the game. Quite often you exit a level into a hub world and are not told what to do. Once in a while you're shown a single image and if you forget what that image is, you'll be searching the entire world until you stumble on what you're supposed to do (if you ever do). There's nothing to really help you remember what you were doing the last time you played the game. All you really get is a vague "go to this map" and that's about all that is said. It feels like it has the flow of a NES era game, yet it was on the Dreamcast. Quite shocking.

The fact is this was an incredible game in 1998, a great game in 2003, but in 2016, this feels like a weak indie title, if not worse. The fact is the game industry has moved on, and Sonic Adventures feels like it's only gone backwards.

A shame because this was one of the better Sonic games, and it was the first really great 3d Sonic game, it just isn't that great now.

I'd recommend it for someone who wants to remember the game, but is willing to realize it's a flawed game/product. I'm not sure if the re release is to blame, or if the original game was as weak a game as what was released on Steam. Either way I'm unable to recommend this to pretty much anyone except the most diehard sonic fans.

Sonic Adventure DX Review!

Overrated af sonic game, if you don't play sonic and never played it don't get your expectations that up, this game is more for nostalgia purposes.

Don't get me wrong its a great sonic game, but its also very overrated. Overrated to the point that people consider it to be better than sonic colors or generations.

Hasn't aged well with some glitches and honestly after playing lost world and coming back it actually feels like lost world is not worse than SADX (if leaving nostalgia behind)

This port isn't that great, but if you download Better SADX (currently at version 3.6), you'll fix all the problems and you'll even be able to play the game at 4k which is awesome!

meh we all know what's the pros and cons of this game but i'll list it anyway
Pros :
+Awesome rock tracks!
+Variety of gameplay
+Bang for your buck when it comes to playtime
+A sonic game with a story that isn't cringe
+Stages are very fun and 1 same stage could be played over and over without getting bored
+Easily moddable, some very fun stage mods guys!
Cons :
-Bad camera, didn't age well at all.
-Glitchy glitchy!!
-Without downloading BetterSADX it's pretty much a horrible port, yeah BetterSADX makes it amazing but this isn't an excuse, if fans can fix this game so can sonic team.

To sum it up i think this is kind of a nostalgia game, new comers could still find enjoyment with the sonic gameplay but isn't guaranteed.

it's more subjective i guess, some people would still give it a 10/10 like it was getting back then, just because i think this game is overrated doesn't mean you wont enjoy it, i guess just give it a try eh?

Final Verdict :
For me i would give it a 7/10, its GOOD, not great, not bad at all. Just my opinion.

For sonic fans out there who are looking for some nostalgia, get this port download BetterSADX (google) and enjoy mods and 4K quality Sonic Adventure!

Despite its few faults, this has always been one of my favourite games since I was a little kid circa the early 2000s. I'm going to be reviewing each of the six stories separately. This will be for the most part spoiler-free, the most I'll do is give a general idea of each storyline. I also won't be going into the general "B" or "A" levels, or missions.

Sonic the Hedgehog
Sonic's story is essentially the most predictable; Robotnik's up to no good and is seemingly in control of a strange monster called Chaos so Sonic needs to collect the seven Chaos Emeralds to stop Chaos. He and his buddy Tails make a couple attempts to track Eggman's airship, and a bit of a runaround ensues. (no pun intended.)
This is definitely the storyline with the most challenge. The levels progressively get longer and more difficult, more noticably in Sonic's story than anyone else's. A major issue I've always had with Sonic in the DX port is that in certain parts of levels, (for example the floating platforms in the second segment of Twinkle Park) moving while jumping is hard to control and feels oddly "floaty". I don't remember if this was present in the Dreamcast version. Other than some other minor physics issues and the nauseating Sky Deck level, Sonic's levels are definitely fun and challenging and there's a lot of opportunities for exploration.

Miles "Tails" Prower
Tails' story is a bit more sweet and simplistic than Sonic's. Tails has always been the one to follow Sonic around, but eventually has to try to learn how to handle situations on his own.
As a little kid I always enjoyed being able to skip parts of levels, so undoubtedly I learned how to skip huge chunks of Tails' levels with ease. His style of flight is probably my favourite flight mechanic out of most games I've played, though it can be more glitchy after you obtain the Jet Anklet. After you learn how to manipulate his style of flight, you can even go through all of his Windy Valley level in one jump.
Something I always found interesting about Tails' storyline is if you listen to the English voice acting, Robotnik sounds a lot more menacing and scary than he did in Sonic's storyline.

Knuckles the Echidna
As the guardian of the Master Emerald, Knuckles lives alone on the floating Angel Island. One night the Emerald shatters and the island crashes into the ocean, so it's Knuckles' job to hunt down the shattered fragments.
Again, more glitches and physics issues to be expected, but the core of the game is pretty old and the DX port is a pretty bad port. But aside from that, Knuckles is probably the most fun gameplay-wise, and he's the easiest to collect tiny animals with for the Chao Garden. His Sky Deck level is still nauseating, though.
There's this one section of Red Mountain where if you stand under a certain rock platform and change the camera to the first-person view, you can see inside of Knuckles' empty head. It's pretty creepy. This trick works with Sonic, too.

Amy Rose
Her story is quite similar to Tails' in terms of trying to become independent. However, in her storyline she's also taking care of a small bird that's being chased down by one of Robotnik's robots.
This storyline is incredibly short, and I honestly feel like it was thrown together quickly to appeal to the young female gamers of the late 1990s. However, Amy's and E-102's storylines do compliment each other very well. The three levels are quite easy, and so is the single boss fight. There's really not a lot to see or do as Amy, but using her hammer flip-jump is extremely addictive.

Big the Cat
Big is a simple cat. He lives in a hut by the river with his frog friend and they fish together. One day, the frog gets posessed by a part of Chaos and Big sets out to get his buddy back.
This is the storyline everyone commonly hates on, but I personally find it even easier than Amy's. The fishing mechanic is really simple, especially since the frog is in the same place in every level, every time you play the level. Despite this, there's actually a lot of optional exploring you can do as Big. There's optional secret areas in Emerald Coast, Ice Cap, and Hot Shelter you can only get to as him. Large character models + '90s physics = no bueno, but luckily you don't have to go through a lot of tight spots as him.
He walks pretty slow but he climbs ladders REALLY fast, which I think is a cute touch considering he's a cat.

E-102 "Gamma"
A robot created by Dr. Robotnik, he's one in the line of the good doctor's new E-100 series robots. He proves that he is the smartest and strongest in the line, but his faulty power source eventually allows him to break out of his programming and rebel against Robotnik.
Tails was my favourite character when I was a little kid, but as I got older I really grew to appreciate E-102. Because he's such an overpowered character, he's essentially given a boss to fight after every level, but it's easy to speed through his levels after playing the game a few times. He does also have the same physics issues that Big has since he's a larger character, but it's a lot more noticable as E-102 because he has to traverse a couple of tight spots, such as the room his story starts in.
I'm a fan of both the original Japanese voice acting and the English dub of the game, but I absolutely adore E-102's English voice. I always thought he sounded so sweet.

This is a crappy port of a nearly 20 year old game, so physics issues and glitches are a given. However, the majority of glitches don't pop up unless you're trying to break the game on purpose. Or, if you're just really unlucky. I've played both the Dreamcast and Gamecube versions of Sonic Adventure, and neither are really as bad as this PC port. It's still playable if you get used to it, but it definitely feels like some of the original coding got "lost in translation", for lack of a better term.
The camera work in this game is definitely not that great, and can be detrimental to a lot of levels if you're not used to how they're laid out.
The music in this game is probably one of my favourite soundtracks, because there's such a variation from techno to rock to folk music. The character themes are probably one of the things that date the game the most, they all sound so much like popular music of the mid to late 1990s that it's actually kind of funny.
Graphics and animation also date the game pretty harshly. If you have Japanese audio turned on, the choreography for cutscenes isn't too bad, but with the English audio it looks and feels a lot like kung fu movie dubbing. That being said, the English dialogue and acting is cheesy, but the voice actors did a great job. I still think Deem Bristow was the best Robotnik.

All in all, while it is a dated game (and I would recommend getting the Dreamcast or at least the Gamecube version over this port), it's a really good game with a lot of variety, and there's a ton to do post-game such as side missions and raising pet Chao. If you like Sonic the Hedgehog, games from the 1990s, or games with a great soundtrack, then this game is a must-buy.
